Graphing Linear Equations: Understanding Coordinates and Plotting Points
To explore the graphing of linear equations, it is important to understand the terms and definitions that will be used in this exercise. A coordinate refers to a value that tells you which way to move from the origin (0, 0) to locate a point on a graph. There is an x-coordinate (move horizontally) and a y-coordinate (move vertically) that make up an ordered pair, which is always written as (x, y).
Find the x and y-coordinates of the points below and write them as an ordered pair:
Write answers as (x, y).
(-2, 630)
Plot the ordered pairs given below and label them with the appropriate letters on the graph provided:
A (3, -4)
B (-5, 0)
C (2, 6)
D (0, -5)
E (-4, 4)
F (33, -4)
