What is the slope of (-5,7) and (1,1)

What is the slope of (2,6) and (8,4)

(1) -1

(2) -1/3 or -1.333333333333333333333333333333333333to infinity

(-5,7) and (1,1)

Slope=-1

(2,6) and (8,4)

Slope=-2/6

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

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
