Is the point (-8,0) a solution to this equation? What are two ways to prove that it is or isn’t? 1) It’s a point on the line !

(-8,0) is also known as the x -intercept of the equation.

Identify the ordered pairs for the x -intercept of each line

What do the four ordered pairs have in common? All x -intercepts have a __________ of ___ y -value 0

How do find the x -intercept if you don’t have the graph? All x -intercepts have a __________ of ___ !!! y -value 0 0

F IND THE X - INTERCEPT FOR EACH EQUATION

(0,3) is also known as the y -intercept of the equation.

Identify the ordered pairs for the y -intercept of each line
