A:
Well, let's see that we can find the midpoint with this formula:[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]We have the midpoint and one of the endpoints so:[tex](\frac{x_1+(-2)}{2},\frac{y_1+(-19)}{2})=(-1,-28)[/tex][tex](\frac{x_1-2}{2},\frac{y_1-19}{2})=(-1, -28)[/tex]We have this now:[tex]\frac{x_1-2}{2}=-1[/tex][tex]x_1-2= -1.2[/tex][tex]x_1-2=-2[/tex][tex]x_1=-2+2[/tex][tex]x_1=0[/tex][tex]\frac{y_1-19}{2}=-28[/tex][tex] y_1-19=-28.2[/tex][tex]y_1-19=-56[/tex][tex]y_1=-56+19[/tex][tex]y_1=-37[/tex]So the pair is (0, -37)
