When you write an equation in the slope-intercept form

the two coefficients m and b represent, respectively, the slope and the intercept.
So, in your case, m=1/4 and b= -7, which leads to the equation

Answer:
15 im positively sure
Step-by-step explanation:
The 6 sides are the same sides
so 6+6=12
add the 3
12+3=15
Volume of cone = pi* r^2 *h/3
If you double the height ;
New volume = pi * r^2 * 2h/3
So, new volume will be twice as much.
