The midpoint of ab =

M(x,y) = (0,0)

Step-by-step explanation:

The endpoints are (2,2) and (-2,-2)

Let's find the midpoint now

=> M(x,y) =

=> M(x,y) =

=> M(x,y) =

=> M(x,y) = (0,0)

(0, 0)

Step-by-step explanation:

(-2, -2) is point B.

(2, 2) is point A.

The center or midpoint of the line is:

(x1 + x2)/2 , (y1 + y2)/2

(2+-2)/2 , (-2+2)/2

0/2, 0/2

0, 0

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.
