Question

What are the coordinates of the midpoint at (-3,9) and (10,18)

Answer 1

Answer:

(7/2, 27/2) or (3.5, 13.5)

Step-by-step explanation:

The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints.

The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

x-coordinate of the midpoint:

(-3 + 10)/2 = 7/2

y-coordinate of the midpoint:

(9 + 8)/2 = 27/2

Answer: (7/2, 27/2) or (3.5, 13.5)
