a boat from A crosses a 100m wide river at a constant speed of 5 m/s with respect to the water flowing at a uniform speed of 1 m/s. Destination B is 80 m upstream from H, a point directly opposites A.

your answer would be fusion

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
