Answer:
The slope is 2
Step-by-step explanation:
There's a theorem: 
So lets put that into our equation.
which also equals 
Then, all we must do is divide the nominator from the denominator.
6/3 = 2
Therefore, the slope is 2!
I hope this helps!

Surface area of a cylinder
The surface area of the cylinder is 219.8 square ft
Step-by-step explanation:
The surface area of a cylinder is defined as the sum of the curved surface are and twice the area of the flat surface
SA = 2πrh + 2πr²
Given Height h = 2 ft
Given Base radius r = 5 ft
Curved Area = 2πrh = 2 × 3.14 × 5 × 2 = 62.8 sq ft
Total Surface Area (SA)= 2πrh + 2πr²
SA = 2 ×3.14 × 5 × 2 + 2 × 3.14 × 5 × 5
SA = 62.8 + 157
SA = 219.8 square ft
Hence the surface area of the cylinder is 219.8 square ft
