First you find the slope using y2-y1/x2-x1
which would be -6 and then to find the y-intercept plug in either (-3,-1) or (-4,-7) in x and y and plug in the slope -6
-1=-6(-3)+b
-1=18+b
-18. -18
-19=b
y=-6x -9
Answer:
The volume of the solid is π/40 cubic units.
Step-by-step explanation:
Please refer to the graph below.
Recall that the area of a semi-circle is given by:

The volume of the solid will be the integral from <em>x</em> = 0 to <em>x</em> = 1 of area A. Since the diameter is given by <em>y</em>, then the radius is <em>y/2</em>. Hence, the volume of the solid is:

Substitute:

Simplify:

Integrate:
![\displaystyle V=\frac{1}{2}\pi \left[\frac{x^5}{20}\Big|_0^1\right]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cfrac%7B1%7D%7B2%7D%5Cpi%20%5Cleft%5B%5Cfrac%7Bx%5E5%7D%7B20%7D%5CBig%7C_0%5E1%5Cright%5D)
Evaluate:

The volume of the solid is π/40 cubic units.
C=25m+75
this is simple y=mx+b (slope intercept form) b is the constant, or 75, no matter what it stays the same. m is the factor that changes, it depends on how many months yous stay with the gym.
