If the endpoints of `bar(ab)` have the coordinates a(9, 8) and b(-1, -2), what is the midpoint of `bar(ab)`? choices: a. (5, 3) b. (4, 5) c. (5, 5) d. (4, 3)

Midpoint

x = (9 - 1)/ 2 = 8/2 = 4

y = (8 - 2)/2 = 6/2 = 3

Answer

D.  

(4, 3)

If the endpoints of `bar(AB)` have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of `bar(AB)`?

solve by using (y₂ + y₁)/2 for midpoint, and (x₂ + x₁)/2

y = (8 - 2)/2 = (6)/2 = 3

x = (9 - 1)/2 = (8)/2 = 4

D. (4,3) is your answer
