Problem 2

Answer 2

Step 1. Define the variables.

x = number of window shades sold
y = Anne's monthly salary in dollars

Step 2. Determine the slope and a point.

Anne gets $6 for each shade, so the slope = 6 dollars/shade.
She sold 200 shades and made $2500, representing the point (200, 2500).

Step 3. Determine the function rule by using the point-slope form.

Step 4. Determine Anne's base salary by substituting x = 0.

App2-2

$1300 is Anne's base salary.
