What are the coordinates of a point located 3 units to the right and 2 units up from the origin?
(3, 2)
(2, 3)
(-3, 2)
(3, -2)
Moving 3 units right increases the x-value by 3, and moving 2 units up increases the y-value by 2, giving (3, 2). This follows the standard Cartesian coordinate convention. Each step along the axes adjusts the corresponding coordinate. Learn more about the Cartesian plane.
In which quadrant is the point (-4, 5) located?
Quadrant II
Quadrant I
Quadrant III
Quadrant IV
Negative x and positive y coordinates place a point in Quadrant II. Quadrant numbering proceeds counterclockwise starting from the positive x, positive y region. This classification helps in quickly identifying sign patterns. See quadrant definitions.
What is the coordinate representation of the x-intercept point located 6 units to the right of the origin?
(6, 0)
(0, 6)
(-6, 0)
(6, 6)
An x-intercept lies on the x-axis, meaning the y-coordinate is 0. Moving 6 units to the right of the origin gives x = 6, so the point is (6, 0). This is the definition of an intercept with the x-axis. Read about intercepts.
What are the coordinates of the midpoint of the segment connecting (2, 3) and (6, 7)?
(4, 5)
(8, 10)
(3, 5)
(5, 4)
The midpoint formula averages the x-coordinates and y-coordinates: ((2+6)/3, (3+7)/2) yields (4, 5). This places the midpoint exactly halfway along the line segment. Midpoint calculations are key in geometry proofs and constructions. Understand the midpoint formula.
What is the distance between the points (1, 1) and (4, 5)?
5
?17
4
?18
Distance on a coordinate plane uses the Pythagorean theorem: ?[(4?1) + (5?1)] = ?(9 + 16) = 5. This measures the straight-line length between two points. Distance formulas are fundamental in analytic geometry. Review the distance formula.
If the point (5, -2) is reflected across the y-axis, what are the coordinates of its image?
(-5, -2)
(5, 2)
(2, -5)
(-5, 2)
Reflection across the y-axis changes the sign of the x-coordinate while the y-coordinate remains unchanged, producing (-5, -2). Reflecting points is a rigid transformation that preserves distance. Reflections are used in symmetry and coordinate geometry problems. Learn about reflections.
Which of these points lies on the graph of y = 2x - 3?
(2, 1)
(3, 4)
(1, 1)
(4, 6)
Substitute x = 2 into y = 2(2) - 3 to get y = 1, so (2, 1) satisfies the equation. Points on a line must satisfy its equation. This checks algebraic consistency with plotted data. Graphing linear equations.
What are the coordinates of a point 5 units from the origin on the positive x-axis?
(5, 0)
(0, 5)
(-5, 0)
(5, 5)
Points on the positive x-axis have the form (r, 0). Being 5 units from the origin along that axis gives (5, 0). Distance from the origin is measured by the absolute value of the coordinate on one axis. Radius and distance.
If a point (x, y) is rotated 90 degrees counterclockwise about the origin, what are its new coordinates?
(-y, x)
(y, -x)
(x, -y)
(-x, -y)
A 90 counterclockwise rotation transforms (x, y) into (-y, x). This is a standard rotation rule in coordinate geometry. Rotations preserve distance from the origin. Explore geometric transformations.
What is the equation of the locus of points equidistant from (0, 3) and (0, -3)?
y = 0
x = 0
y = 3
x = 3
The set of points equidistant from (0, 3) and (0, -3) lies on the perpendicular bisector of the segment joining them, which is y = 0. This is the definition of a locus in analytic geometry. Perpendicular bisectors form boundaries of equidistance. Understanding loci.
A triangle has vertices at (0, 0), (4, 0), and (4, 3). What are the coordinates of its centroid?
(8/3, 1)
(4/3, 1)
(2, 1)
(3, 1)
The centroid formula averages the x-coordinates and y-coordinates of the vertices: ((0+4+4)/3, (0+0+3)/3) = (8/3, 1). The centroid is the intersection of medians in a triangle. It balances the triangles area equally. Learn about centroids.

Cheat Sheet
Coordinate Plane Foundations -
Review the horizontal x-axis and vertical y-axis that meet at the origin (0,0) to orient every point. Think "Right and Up Positive" as a handy mnemonic endorsed by educational sites like Khan Academy. Mastering this layout is key whether you're preparing for a coordinate plane quiz or you plot coordinates online for the first time.
Precise Point Plotting -
Always list the x-coordinate first, then the y-coordinate when you plot points on a grid to avoid common mix-ups. For example, the point (3,-2) lies three units to the right and two down from the origin. Practicing this simple pattern on online graphing coordinates tools solidifies your spatial intuition.
Distance Formula Essentials -
Use the distance formula d=√((x₂−x)²+(y₂−y)²) to calculate the straight-line length between two points, a principle rooted in the Pythagorean theorem. For instance, the distance between (1,2) and (4,6) is √((4−1)²+(6−2)²)=5. Refer to university resources like MIT OpenCourseWare for step-by-step derivations.
Slope as Rise over Run -
Compute slope as m=(y₂−y)/(x₂−x) to measure the steepness of a line, remembering the "rise over run" mnemonic. Between (2,3) and (5,11), the slope is (11−3)/(5−2)=8/3, showing a steep incline. This concept is crucial when you check your answers on online graph coordinates tools.
Graphing Lines with y=mx+b -
Master the slope-intercept form y=mx+b to swiftly graph lines by starting at the y-intercept b and applying the slope m. For example, y=2x+1 starts at (0,1) and uses a rise of 2 and run of 1 to mark another point. Plotting these lines correctly on online graphing coordinates platforms builds confidence for any coordinate plane quiz.
