Use the vertical line test to determine which graph represents a function

make a line and drag it over the shape if you see more than 2 points over the line then it is not a function if you see only 1 point over the line it is a function

Step-by-step explanation:

x-3y=4

step-by-step e

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
