Answer:
Explanation:
Points given:
- M(-5, 0) - midpoint
- A( -8, 5) - endpoint
- B(x, y) - endpoint
Use midpoint formula to find the coordinates of B:
- x = (x1 + x2)/2, y = (y1+ y2)/2
Substitute known values and solve for x and y:
- -5 = (-8 + x)/2 ⇒ -10 = -8 + x ⇒ x = -10 + 8 ⇒ x = -2
- 0 = (5 + y)/2 ⇒ 0 = 5 + y ⇒ y = 0 - 5 ⇒ y = -5
Point B is:
