Which letter represents the slope in the slope-intercept equation of a line:
y = mx + b?

M=slope and the B is the starting point or y intercept

The y-intercept is represented by the letter b.

Step-by-step explanation:

In the slope-intercept equation:

x and y = points on graph

m = slope

b = y-intercept

Draw a diagram to illustrate the problem as shown below.

Calculate the volume of the empty cone.
V₁ = (1/3)π*(6 in)²*(10 in) = 120π in³

Calculate the volume of the sphere.
V₂ = (4/3)π*(1.5 in)³ = 4.5π in³

The volume that can be filled with flavored ice is 
V = V₁ - V₂ = 115.5π in³ = 362.85 in³

Th volume is 115.5π in³ or 362.9 in³ (nearest tenth)
