Answer:
slope of r = -9/4
slope of Q = 4/9
Step-by-step explanation:
x1 y1 x2 y2
10 6 1 2
(Y2-Y1) (2)-(6)= -4 ΔY -4
(X2-X1) (1)-(10)= -9 ΔX -9
slope= 4/9
So, the man is 6 feet, but casts a 9 foot shadow. So, you divide 25 by 9, and then you would find it goes into it 2.8 times, so round and get 3 if you want,or keep it. And then 12, or round to 13.
