How do you graph linear equations

Look At the y over x. X is how many places you move on the x-axis. Y is how many places that you move up. So you would repeat that where the Y intercept is.

Step-by-step explanation: for example: y=2x+1. You would move up 2 places and over on the X axis one place, and since 1 is the Y-intercept that is where it would intercept on the Y-axis.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
