You multiply -4 to everything inside of the parenthesis which is 20w+12u-8

Explanation
when you know the slope and a passing point of the line, you can find the equation of the line by replacing in the slope-point equation ,it is given by:

then
Step 1
a)Let

now,replace and solve for y

therefore, the answer is

I hope this helps you

The answer to this question is
B.The new volume will be 8 times the original volume.
So the formula is: (x-h)^2+(y-k)^2=r^2
(x-11)^2+(y+9)^2=144
