Nicole has a rectangular canvas that is 12 inches long and 10 inches wide. she paints a blue square in the center of the canvas. the square is 3 inches on each side. how much of the canvas is not painted blue?

∞ this is your sign

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
