I will give brainliest and full points just pls help...

How do you find the slope of a line?

H!

So the formula for slope is y=mx+b

M=slope

b= y-intercept

x and y = the intercept ie. (4,5)

Here's a example formula

5=m x 4+ the y intercept

If you want, use the slope intercept formula!

Trust me it's much more work, but it's harder to mess up and get the incorrect answer.

Good luck!

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
