Question

[Due TOMORROW] In the standard (w.y) coordinate plane, the point (3,-7)
is the midpoint of the line segment with endpoints
(9.-11) and:

Answer 1

(6,-9) it is 3 units away from both 3 and 9, and -9 is 2 units away from -7 and -11.

Answer 2

Answer:

• (- 3, -3)

Step-by-step explanation:

Use midpoint formula to find the coordinates of the other end point:

• (9 + x)/2 = 3 ⇒ 9 + x = 6 ⇒ x = - 3
• (-11 + y)/2 = -7 ⇒ -11 + y = -14 ⇒ y = - 3
