Suppose you threw a Frisbee and it landed on your roof, caught in the rain gutter. You want to know how high off the ground it is to the
rain gutter to determine if a 12-foot ladder will suffice. You walk ten feet away
from the house to place your mirror on the ground, and then walk another five feet until you see the gutter in the
mirror.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
