Question

A) y=6x-7
B) y=1/4x+8
C) y=4x+8
D) y=-1/4x-7

Answer 1

Symmetry? lol

I guess you would need to find the perpendicular.
The slope of that line is 4.

The negative reciprocal is -1/4.

Now what's confusing now, is that both D and B works because the intercept does not influence symmetry between the two lines; only the linear slope does. I can't help with that.

Answer 2

C. 4(-3)+8 = -12+8 = -4.
