Best ResponseYou've already chosen the best response.0mirror being mid point of the line joining the two points. \[\left\{ 5,11 \right\}\] now \[5=\frac{x2x1 }{ 2 }\] and \[11=\frac{ y2y1 }{ 2 }\]

Best ResponseYou've already chosen the best response.0I completely understand what you're saying, but I honestly have no idea how to solve for x2 and y2. I remember learning this, but I haven't used it in 2 years.
