Answer:
Step-by-step explanation:
The slope intercept form of a line is given by
Here m is the slope and b is the y intercept.
Now, the slope can be defined as the ratio of rise and run.
It has been given that at the curb a ramp is 11 inches off the ground. It means the rise is -11.
Now, other end of the ramp rests on the street 55 inches straight out from the curb. Hence, run is 55.
Therefore, the slope is given by
Therefore, the linear equation is
Also, from the second condition, we have a point (55,0)
Therefore, the linear equation is
