The midpoint of AB is M(3,-2). If the coordinates of A are (1, -3), what are the coordinates of B?

23 just took the test

Step-by-step explanation:

B(5,-1)

Step-by-step explanation:

So, x1=1 and x2=x. And y1=-3 and y2=y.

So,

(1+x)/2=3, then manipulating it gives x=5.

And,

(-3+y)/2=-2, then manipulating the equation gives y=-1.

Hence B(5,-1)

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
