MIDPOINT AND LINE LENGTH

WILL GIVE 70 MORE IF CORRECT

so midpoint formula is (x1+x2/2, y1+y2/2)

Step-by-step explanation:

so for 1: (11-11/2, 4+12/2)= (0,8)

then if you have the midpoint and one endpoint, find the distance between them to find the other endpoint.

so, for the third example, start with the x. how fair is -8 from -1? The answer is 7. So, we must ask, what number is 7 more than -1? Answer is 6. Then repeat for the y. 6 is 5 units away from 1, so then we do 1-5=-4. So it should be (6,-4) as point B
