Answer:
-7
Step-by-step explanation:
You have to isolate the variable so you need to add 7z and 9 to both sides. You then get y+ 7z+ 9= 7x. Then divide 7x from both sides. The equation becomes x= y/7+ z + 9/7.

(-4.25 + 2.5)/2 = -1.75/2 = -0.875
C is correct
m = 1.49
b = 5.50
equation y = 1.49x + 5.50
Non-proportional
Positive Slope
