Point Y is (6, -1)
Subtract 6 from the y coordinate in point y since it is translated down. keep the x coordinate since it is only being translated up and down, or by the y axis
The answer is C
10% = 0.10
12 x 0.10 = 1.20
12 - 1.20 = 10.80
.6578 this would be the answer
The slope of the line would be 5x.
