Question

Find the midpoint of a segment with endpoints A(-3,10) and B(9,2).

Answer 1

(3, 6)

Explanation:

To calculate the midpoint use the midpoint formula

midpoint = [
`(1)/(2)`(
`x_(1)` +
`x_(2)`),
`(1)/(2)`(
`y_(1)` +
`y_(2)`) ]

with (
`x_(1)`,
`y_(1)`) = (- 3, 10) and (
`x_(2)`,
`y_(2)`) = (9, 2)

Hence

midpoint = [
`(1)/(2)`(- 3 + 9),
`(1)/(2)`(10 + 2) ]

= (3, 6)

Answer 2

(3, 6)

Explanation:

You add the x points together and divide by two, then you add the y points together and divide by 2.
