A rectangle with integer side lengths is divided into four smaller rectangles The perimeter of the largest and smallest of these rectangles are 28cm and 12cm

Which of the following is a possible area of the original rectangle

28/2=14

12/2=6

So it's half perimeter is 20

By trial and error the only possible solution is

8 * 12 = 96

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
