Set equal to eachother
(2x+1) = 79
Subtract 1 from both sides
2x=78
Divide 2 from both sides
2x/2=78/2
X= 39
Hmmm I think either D or C

Therefore, the slope of the line is 1. In case if you want to know the equation.

Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.

It's the same, you can use any orders given.
Overall, the slope is 1 and the equation is y=x+10
if ya asking for simpliicatio
remember that

Answer:
803.84 in^3
Step-by-step explanation:
First of all we have to find the base area
base area = radius^2 x 3.14 = 8^2 x 3.14 = 64 x 3.14 = 200,96 in^2
the volume can be find with this formula:
V = (base area x height)/3
V = (200.96 x 12)/3 = 803.84 in^3
