Y=mx+b
Y= -14(x-5)+4
Y= -14x+70+4
Y= -14x+74
Plot (0,74)
Then move down 14 then over left 1
The answer to the question is 33.3
Direct variation always has the relationship y=kx. Indirect inverse variation always has the relationship y=k/x.
In this case y=kx, where k=6, so this is a direct variation.

Slope: (6-4)/(3+1) = 2/4
The slope is 1/2
