Question

amar is using a laser printer to print a report. the line on the graph shows the relationship between x, the number of minutes the machine spends printing, and y, the number of pages that are printed. what is the constant of proportionality for the line representing this relationship? type your response in the box below.

Explanation:

Step1: Identify proportionality

The line passes through (0,0), so \( y = kx \) where \( k \) is the constant.

Step2: Pick a point from the graph

Choose (7,28) (since at x=7, y=28).

Step3: Calculate k

\( k = \frac{y}{x} = \frac{28}{7} = 4 \).

Answer:
