Answer:
the slope is 5.
using Y = mx+b. you know that m will be your slope and b will be the y - intercept.
Answer: 
Step-by-step explanation:
We see that g(x) is a straight line that passes through the origin, just like f(x), so g(x)=kx for some constant k.
Since g(x) passes through (4,2), we know that 2=4k, and thus k=1/2.
So, 
Volume of a cylinder formula is
