Point slope form is y - y1 = m (x - x1), so the point on the line is (-7, 3).
You can plug the point back in the check. Slope is given.
y - 3 = 4 (x- (-7))
y - 3 = 4 (x + 7)
It's correct, so you know that B (-7, 3) is the answer.
Step-by-step explanation:
Since one of the boundaries is y = 0, we need to find the roots of the function 
. Using the quadratic equation, we get
But since the region is also bounded by 
, that means that our limits of integration are from 
(instead of -3) to 
.
Now let's find the volume using the cylindrical shells method. The volume of rotation of the region is given by
