Question

Given D (6, 6) and M (2,4) find E

Answer 1

Is M a midpoint and E an end point?

Answer 2

it doesn't say

Answer 3

What is the exact problem?

Answer 4

(-2, 2)

Answer 5

Looks like M(2,4) is the midpoint of the line segment joining D(6,6) to E(x,y). If so, then the objective is to find the right x and y that will satisfy that condition. The sequence D(6,6), M(2,4), E(x,y) must be an arithmetic profression whose common difference d is (2,4) - (6, 6) = (-4, -2). To get from M to E add d to M
(x,y) = (2, 4) + (-4, -2) = (-2, 2).
Then E is located at (-2, 2).
