Which set of ordered pairs does not represent a function? A{(-4,3), (8,3), (-2, 3), (7,7)}
B{(-2,-5), (0, -2), (9,9), (2,1)}
C{(9,3), (5, 4), (3, 3), (-6,3)}
D{(6,1), (8,2), (-4,5), (6,3)}

A and C

Step-by-step explanation:

By  finding the areas of rectangles using the coordinates above, the following does not represent their functions

A) (-4,3), (8,3), (-2,3), (7,7) and C) (9,3), (5,4), (3,3), (-6,3)

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. : )
