1. The answer is either letter A or letter B
Graph the relation {(5, 0), (0, 5), (5, 1), (1, 5)}. Is it a function? Why or why not?

A. No, it does not pass the vertical-line test..

B. No, it does not pass the horizontal-line test.

C. Yes, it passes the horizontal-line test.

D. Yes, it passes the vertical-line test.

A. No, it does not pass the vertical-line test..

Step-by-step explanation:

A. is the correct answer, as functions cannot have the same x value correspond to different y values. For a function to be considered a function, it must always pass the vertical line test.

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. : )
