Answer:
The left end of the cable is 15 m above the roadway
Step-by-step explanation:
Let
x----> the horizontal distance from left end of cable (m)
y----> the height above roadway (m)
we know that
The y-intercept is the value of y when the value of x is equal to zero
In this problem
The y-intercept is the height above roadway (m) when the distance from end of cable is equal to zero
so
The y-intercept is the point (0,15)
so
The left end of the cable is 15 m above the roadway
