Question

(PLS HELP MY TEACHER WANTS ME TO PASS THIS!) Which line on the graph is the image of the line y = 2x after a transition of 3 units along the x-axis and 4 units along the y-axis?

Line A

Line B

Line C

Line D

Answer 1

The answer is line a

Answer 2

Line y=2x ==> No matter what value Y gets, X is always half of it

But X was transitioned by 3 units and Y by 4, so let's pull them back down

==> y-4 = 2x-3

Upon verifying each of the lines with y = 6:

A. 6-4 = -4-3 ==> 2 = -7. A falls

B. 6-4 = 4-3 ==> 2 = 1. B falls, but this one's the closest to truth

C. 6-4 = 8-3 ==> 2 = 5. C and D will obviously fail because X is so far ahead.

Out of testing, B is the only correct answer, despite the answers being close instead of true
