Question

What are the coordinates of Q, if the midpoint of is (2, 4) and the coordinates of P are (5, 9)?

Answer 1

\[\huge \text{midpoint} \; = \; (\frac{x_1 + x_2}{2} \; , \; \frac{y_1 + y_2}{2})\]
\[\huge (2, 4) = (\frac{5 + x}{2} \; , \; \frac{9 + y}{2})\]
solve for x first
\[2 = \frac{5+x}{2}\]
then solve for y
\[4 = \frac{9+ y}{2}\]
do you get it?

Answer 2

some what

Answer 3

nice. so tell me what you get for x and y
