Question

a ramp is extended from a truck to the ground. the ramp has a slope of 7/16. if y is 3.5 feet, what is , in feet?

Answer 1

We know the slope, m, is (7/16), and the y-intercept, b, is 0, for it starts from the ground.
y=mx+b
y=(7/16)x+0
y=(7/16)x
We need to know what x value will obtain y=3.5, so get x alone.
3.5=(7/16)x
What did you get?
