Coordinate Plane Quiz - Practice Test Cheat Sheet
- Cartesian Coordinate System - Welcome to your math map! The Cartesian plane is made up of a horizontal x-axis and a vertical y-axis that cross at the origin (0,0). Every point is an ordered pair (x,y), like (3, - 2) which means 3 units right and 2 units down. Symbolab Guide
- Plotting Points - Grab your pencil and start at the origin, slide along the x-axis to your x‑value, then move straight up or down to hit the y‑value. It's as easy as "right 4, up 5" for (4,5)! Practicing this will make you a plotting pro in no time. Coordinate Plane Notes
- Four Quadrants - The plane is divided into I, II, III and IV. Each quadrant tells you the sign of x and y: I (+,+), II ( - ,+), III ( - , - ) and IV (+, - ). Knowing this helps you instantly know where a point lives and what its signs should be! Coordinate Plane Notes
- Distance Formula - Imagine connecting two points with a straight "math rope." Use d = √[(x₂‑x)² + (y₂‑y)²] to measure its length. For example, between (1,2) and (4,6) you get √[(3)²+(4)²] = 5 units. Byju's Formulas
- Midpoint Formula - Want the exact halfway point? Use M = ((x+x₂)/2, (y+y₂)/2). Between (2,3) and (4,7) you land at (3,5). It's like averaging each coordinate - super handy for bisecting lines. Byju's Formulas
- Slope Calculation - Slope is your line's "rise over run": m = (y₂‑y)/(x₂‑x). This tells you how steep your line climbs or falls. For (1,2) to (3,6), m = 4/2 = 2, so you rise 2 for every 1 you run. Byju's Formulas
- Slope-Intercept Form - This is y = mx + c, where m is slope and c is the y‑intercept. It's like a line's secret identity: for m=2 and c= - 3 you get y = 2x - 3. Plot the intercept and use slope to draw the rest! Byju's Formulas
- Section (Division) Formula - Divide a line segment in a ratio m:n with P = ((mx₂ + nx)/(m+n), (my₂ + ny)/(m+n)). It's perfect for splitting paths like a boss - no guessing, just pure math precision. Byju's Formulas
- Triangle Area via Vertices - Compute area with ½|x(y₂−y₃) + x₂(y₃−y) + x₃(y−y₂)|. For (1,2), (4,5) and (6,3) you get 6 square units. It's like plugging into a magic determinant formula! Byju's Formulas
- Parallel & Perpendicular Slopes - Parallel lines share the same slope (m = m₂), while perpendicular ones multiply to - 1 (m·m₂ = - 1). So if one line has m=2, its perfect partner stands at m= - ½. Math match made easy! Byju's Formulas
