Midpoint formula: (x1+x2)/2, (y1+y2)/2
(1+5)/2 = 6/2 = 3 for x
(5+2)/2 = 7/2 = 3.5 for y
Midpoint: (3,3.5)
Answer: slope is 1/3
Step-by-step explanation: make a graph of y=1/3x+9
Simplifyiing
the greatest common factor is 3 so
3x - 9y + 12 = 3(x - 3y + 4)
No such thing ,But what you can do is is go on Cymath and it will help you solve it
