Hope this year is useful!!
Slope: 3
Y intercept: 11 or (0,11)
Equation: y = 3x + 11
The slope should be 3/2, since you rise 3 and go over 2
i can only help you with the volume of #5.
So the volume of a cylinder is = πr²h.
First , put the numbers in the equation.
π(6)² (14)
Next you solve.
π(6)²(14) = 36 (14) π = 504π
V= 504π
