Best ResponseYou've already chosen the best response.0\[\large Midpoint(x,y) = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\] Here: \((x,y) = (3, 5)\) , \((x_1, y_1) = (6, 3)\) and we have to find \(x_2\) and \(y_2\) \[\large Midpoint(3,5) = (\frac{6 + x_2}{2}, \frac{3 + y_2}{2})\] Try to equate x coordinate of Left side with the right side.. Similary do for y coordinates on both the sides.. and find \(x_2\) and \(y_2\)...

Best ResponseYou've already chosen the best response.1for x, what do you need to add to 6 so when you divide it by 2, you get 3? the same technique for y.

Best ResponseYou've already chosen the best response.0Simply solve this: \[\frac{6 + x_2}{2} = 3\] Multiply 2 both the sides and then add 6 both the sides and tell me what are you getting for \(x_2\)..
