    So you have \(\dfrac{-1+x_2}{2}=-6\) and \(\dfrac{-4+y_2}{2}=3\). Solve for \(x_2\) and \(y_2\) and you answer is \((x_2, y_2)\)

    So (-1, 2) and (-2,2) ?

    \(\dfrac{-1+x_2}{2}=-6\implies -1+x_2 = -12\implies x_2=-11 \)

    Do something similar to get \(y_2\)

    Thank you both, I have a ton of questions that involve distance formula and I am not good at any of them

    The midpoint between \((a,b)\) ad \((c,d)\) is \((\dfrac{a+c}{2},\dfrac{b+d}{2})\)
