Question

Point M is the midpoint of AB. If the coordinates of point Mare (2, 8) and the coordinates

of A are (10, 12), what are the coordinates of B?

Answer 1

(-6,4)

Explanation:

add the x coordinates of point A and B(take x coordinate of B as X),then divide the sum of 2 and equal it to 2 which is the x coordinate of the midpoint.

then repeat the same procedure for the y coordinates ,take the sum of y corrdinates divide by 2 and equal to 8.

then u can obtain the coordinates of B.
