The slope is 4/5. You can use the method: y=mx+b
Answer:

Step-by-step explanation:
Cylinder volume formula is 




Cos(angle) = Adjacent Leg / Hypotenuse
cos(35) = 9 / x
x = 9 / cos(35)
x = 10.99
Rounded to nearest tenth = 11.0
He can conclude that the system of equations has no solution since one equation in it always results with false equivalency.
