7. A triangle and a rectangle have the same perimeter. The sides of the triangle are x, x+1, and x + 2. The sides of the rectangle are x – 3 and x + 1.
Find the dimensions of each figure and then find the perimeter of each.

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
