Speed = distance / time
Speed = 50 miles / 4 hours
Speed = 12.5 miles per hour
Gradient (m) = change in y/change in x
-2-5/0–2 = 3.5
gradient (m) = 3.5
Now evaluate one of the coordinates and the gradient in the equation
y = mx + c
-2 = 3.5(0) + c
c = -2
so the answer is
y = 3.5x -2
Answer:
A = 192
