Answer:
The other end point is [tex](-3,5)[/tex]
Step-by-step explanation:
For two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
The mid point[tex](x,y)=((x_1+x_2)/2,(y_1+y_2)/2)[/tex]
For the mid point [tex](x,y)=(-1,1)[/tex]
and [tex](x_1,y_1)=(1,-3)[/tex]
[tex](x_2,y_2)=?[/tex]
[tex](-1,1)=((1+x_2)/2,(-3+y_2)/2)[/tex]
[tex](1+x_2)/2=-1\\\\1+x_2=-2\\\\x_2=-2-1\\\\x_2=-3[/tex]
And
[tex](-3+y_2)/2=1\\\\-3+y_2=2\\\\y_2=2+3\\\\y_2=5\\[/tex]
So, the other end point is [tex](-3,5)[/tex]
