19. The coordinates of the endpoints of AB in the standard (x, y) coordinate plane are (9,-2) and (-5, 8).
What is the x-coordinace of the midpoint of AB?
A. -2
B. 2
C. 3
D. 4
E. 7

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

i think the correct option is the second option.
