Question

If M is the midpoint of XY, find the coordinates of X if MI-5, 10) and I(-8, 6).

Answer 1

(-2,14)

Explanation:

The midpoint is the middle of a line, meaning that its coordinates is equal to the average of 2 points on the line.

That means that (-5,10) is equal to (
`\frac{x-8}2`,
`\frac{y+6}2`).

Calculating this is easy enough, doubling both numbers to get

-10=x-8

-2=x

20=y+6

14=y
