Aplumber charges a $45 fee to make a house call and then $25 for each hour of labor. the plumber uses an equation in the form y = mx + b to determine the amount to charge each customer. what is the value of m in the equation?

m = $25

Step-by-step explanation:

The equation that the plumber is using 'y = mx + b' represent a linear equation.  A linear equation shows a relationship between two set of data where the change is constant.  In the case of the plumber, his rate is $25 per hour, so for every hour, he charges the same amount.  So, as each hour increases, the rate increases another $25.  In the equation y = mx + b , y = the total (dependent variable), m = rate of change, x = the number of hours (independent variable) and b = initial value.  The $45 fee is the initial value or charge regardless of the number of hours worked.  So, m = $25, which is the rate per hour.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
