Which equation is being represented by this line?

• y = -1x + 2

• y = 1/2x + 2

• y = 3x -4

• y = -3x +2

The explicit equation for the function is:

• f(x) = 3x + 2

• f(x) = 3x -1

• f(x) = 3x + 5

• f(x) = 5x + 3

A taxi company charges a flat fee of $3 plus $2 per mile driven. Write the function that represents the total cost (C) as a function of the number of miles driven (m). Then, interpret the rate of change and the initial value.

• C(m) = 2m + 3

• C(m) = 3m + 2

• C(m) = 4m + 1

• C(m) = 5m + 2

The explicit equation for the function is:

• f(x) = 4x - 2

• f(x) = -2x + 4

• f(x) = 6x + 4

• f(x) = 4x + 6
