Question 1133604: how can you find the last end point of a line when M= (2,5) AND A=(2,3) M
equals the midpoint and A equals one of the endpoints. How would you find the last endpoint which would be B??

The midpoint is the average of the endpoint values. That means that M=(1/2) (A+B)
so for M=2 (x-value), (1/2)(A+B)=2 and A+B=4. If A is 2, B has 2 for x value.
For y, 5=(1/2)(3+B), so 10=3+B, and B=7
(2, 7)
