Solve for variable: 2(r-3)/4 -8 =50

Hello!

Let's begin by multiplying all 3 terms by 4, to remove the fraction:

2(r-3) - 8(4) = 50(4)

Then 2r - 6 - 32 = 200. Consolidating the constants on the right side, we get:

2r = 162. Solving for r, we divide both sides by 2, obtaining r = 81 (answer)

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
