It is a function. It passes the vertical line test, meaning for each x there's at most one y.
When x=2 we see y=-3 as (2,-3) is a point on the graph

Answer:
V=11858.98
Step-by-step explanation:
V=r^2*pi*h
first find r
r=d/2
d=1.4(19.75)
d=27.65
r=27.65/2
r=13.825 ft
plug into volume equation
V=13.825^2*pi*19.75
V=11858.97771
V=11858.98 ft^3
Answer: x=-5, y=9
You can use elimination to solve this system. By adding the two equations together, you get:
-x=5
Then solve for x by dividing both sides by -1:
x=-5
Now that you have x, substitute that into one of the equations to solve for y.
6(-5)+5y=15
-30+5y=15
5y=45
And now divide both sides by 5 to solve for y:
y=9
