Standard geometry…
here we go….
-5=-3+x/2
-5*2=-10+-3=-13
x=-13
-1=7+y/2
-1*2=-2-7= -9
y=-9
endpoint<-13,-9>
definatly deserves best answer!

midpoint formula is M(x1 +x2/2,y1+y2/2)
so work the x cooridinate: -3=5+x2 divided by 2
multiply both sides by 2
-6=5+x2
add 6
11=x2
then do the same for y

ok so I look at it this way. Let’s do the x value first.
the midpoint value is -3, so (5 + x)/2 = -3. x = -11.
do the same for y.
midpoint value = 7, so (-1+x)/2=7. y = 15.
therefore the other point is (-11,15)
Hope i helped you out.
