Answer:
where's the question I'm confused
10 is proportional, while 11 is not. The answer for 10 is 1.5.
First and last ones
The " = [number] " at the end of an equation for a circle is the radius squared
So if the diameter is 12, then the radius is 6, and 36 is 6 squared
Also as long as the x term doesn't have an integer affecting it (like -3 or +5) then it'll stay on the y axis.
