ANSWER:

A. Function C

B. Function B

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope and y-intercept form is the following

[tex]\begin{gathered} y=mx+b \\ m\text{ is the slope and b is the y-intercept} \end{gathered}[/tex]

Where the slope can be calculated as follows:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We must calculate the equation for each function.

Function A:

[tex]\begin{gathered} m=\frac{15-0}{6-0}=\frac{15}{6}=\frac{5}{2}=2.5 \\ b=0 \\ y=2.5x \end{gathered}[/tex]

Function B:

[tex]\begin{gathered} y=3x-1 \\ m=3 \\ b=-1 \end{gathered}[/tex]

Function C:

[tex]\begin{gathered} m=\frac{4-2}{6-0}=\frac{2}{6}=\frac{1}{3}=0.33 \\ b=2 \\ y=0.33x+2 \end{gathered}[/tex]

The linear function has the greatest initial value is the function C, b = 2

The linear function has the greatest rate of change is the function B, m = 3
