Question

S is the midpoint of RT. T has coordinates (-14,-15) and S has coordinates (11,-1) Find the coordinates of R

Answer 1

(36, 13)

Explanation:

to find the midpoint you have the add the x and the y and then divide by two

to find one of the endpoints you just do the opposite

you multiply the midpoint by 2

and then subtract the remaining endpoint from it

(11, -1) --> (22, -2)

now subtract T from it

(36, 13)

that is your answer
