Answer:
y=x−3
Step-by-step explanation:
Flip the equation.
4y+7=4x−5
Add -7 to both sides.
4y+7+−7=4x−5+−7
4y=4x−12
Divide both sides by 4.

y=x−3
ik this doesnt make any sense but hope this helps :/

For this question, you would have to use the midpoint formula.
(X1 +X2 / 2 , Y1 + Y2 / 2)
In other words,
(9 + -3 / 2 , -7 +5 / 2)
(6 / 2 , -2 / 2)
(3 , -1)
Your midpoint is (3, -1)
