Question

"To paint a house, a painting company charges a flat rate of $500 for supplies, plus $50 for each hour of labor. Find the slope of the line if you were to graph it."

Answer 1

The slope of the line representing the painting company's charges is $50 per hour of labor.

Step-by-step explanation:

The slope of the line that represents the cost to paint a house given by the painting company is obtained by identifying the rate of change in cost with respect to the hours of labor. In this scenario, the flat rate of $500 is the y-intercept, as this is the cost when no labor hours have been worked. The cost increases by $50 for each additional hour of labor, which means that $50 per hour is the slope of the line.
