The answer to that question is four
This answer is pretty simple. you see (5,-8) and (20,y). well the 20 is 4 times the 5 on the x value so multiply the y value by 4 to get your answer which Y=-32 in the 2nd corrdenants.
-13m = -377
m= -377/-13
m=29
the negatives cancel out. so just do 377/13 which equals 29
