Answer:
F=0.4t
Step-by-step explanation:
Find the slope using the formula rise over run or y2-y2 over x2-x1
y2=72 y1=64 x2=25 x1=5
72-64/25-5=8/20=0.4
F(1)=2(1)-1
f(1)=2-1
f(1)=1
It depends how you name the sides of triangle.
Look at picture at the result.

PS. Sorry for my terrible drawing but I did it as fast as possible :)
