At the curb a ramp is 11 inches off the ground. The other end of the ramp rests on the street 55 inches straight out from the curb. Write a linear equation in slope-intercept form that relates the height y of the ramp to the distance x from the curb.

y = 5x + 11

y = - 1/5x + 11

y = - 1/5x + 55

y = 1/5x + 55

Keaton Hammond · Answer 1

Slope of the ramp=y/x

=11/55

=1/5

General equation;

y=mx+c

y=1/5x+c

Replacing for x and y;

11=1/5*55+c

c=0

The equation then should be;

y=1/5x
