Question

how would i write (8,1),(2,3) in a equation midpoint
what number would i substitute

Answer 1

x+x/2 , y+y/2
8+2=10/2=5
1-3=-2/2=-1
(5,-1)

Answer 2

the answer is (5,2) but when itry to do substitute part im confused

Answer 3

y=mx+b
find slope with the two points y-y/x-x
input slope for m
input x and y for their places in the y=mx+b equation and solve for b
then rewrite without the x and y. only inputing the m and b that you found

Answer 4

thanks
