Rectangle PQRS has vertices at P(-3, 5), Q(8, 5), R(8, 0) and S. The coordinates of point S are

(-3,0)

Step-by-step explanation:

The two points that are located on the line y=5 are (-3,5) and (8,5), so the other two points have to be on the same line y=0 because of the y coordinate in (8,0). The shape is a rectangle so the the distance between (-3,5) and (8,5) will be the same as (8,0) and S. So, S has to be at (-3,0).

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

answer: 180 degrees clockwise
