Eric is hiring a company to install carpeting in his house. The company charges a one-time installation fee plus a certain amount per square yard of carpeting. The graph below shows the relationship between the number of square yards of carpeting and the total cost, in dollars.
A. Slope of the graph
B. Y-intercept of the graph
C. Domain of the function
D. Range of the function

A slope in a graph can mean a increase or a decrease in whatever. For example a decrease in miles per hour (mph), business sales, and more. Also don't forget slopes with decrease are negative slopes and slopes with increase are positive slopes. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right. It's important to note that we work from left to right when dealing with slope.

The graph of a linear equation is a straight line.

The quantity that represents the cost per square yard of carpeting is the (a) slope of the graph.

The slope of the graph is the rate of change of the total cost over the change in square yard.

This means that:

The slope of the graph is the cost per square yard of the carpet.

Hence, the required quantity is (a)
