How do I solve this?

Answer:

The other end point is (-3,5)

Step-by-step explanation:

For two points (x_1,y_1) and (x_2,y_2)

The mid point(x,y)=((x_1+x_2)/2,(y_1+y_2)/2)

For the mid point  (x,y)=(-1,1)

and (x_1,y_1)=(1,-3)

(x_2,y_2)=?

(-1,1)=((1+x_2)/2,(-3+y_2)/2)

(1+x_2)/2=-1\\\\1+x_2=-2\\\\x_2=-2-1\\\\x_2=-3

And

(-3+y_2)/2=1\\\\-3+y_2=2\\\\y_2=2+3\\\\y_2=5\\

So, the other end point is (-3,5)
