Question

What us the midpoint of A(-8,2) and B(4,-2)​

Answer 1

Answer:

(-2 , 2)

Step-by-step explanation:

A(-8 , 2) = (x1 , y1)

B(4 , -2) = (x2 , y2)

midpoint = (x1 + x2/2  ,   y1 + y2/2)

=(-8 + 4/2  ,  2-(-2)/2)

=(-4/2  ,  2+2/2)

(-2  ,  2)

(3 , 7) = (x1 , y1)

(9 , 2) = (x2 , y2)

distance of PQ = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

=$\sqrt{(9 - 3)^2 + (2 - 7)^2}$

=$\sqrt{(6)^2 + (-5)^2}$

=$\sqrt{36 + 25}$

=$\sqrt{61}$
