Question 6
An air-conditioning and heating company has a fixed monthly cost of $3000. Furthermore, each service call costs the company $20.
Write an equation in slope-intercept form to represent the total cost for 1 month, y, if x service calls are made during the month.
y=

Answer 1

For each service call cost of 20$ will be added to fixed cost of 3000$.

Explanation:

The total cost for 1 month is the sum of the fixed monthly cost and the cost of all the service calls, so we can write the equation as:

y = 3000 + 20x

This equation is already in slope-intercept form, where "y" is the dependent variable, "x" is the independent variable, 3000 is the y-intercept (the point where the line crosses the y-axis, when x=0), and 20 is the slope of the line.

This equation can be interpreted as

For each service call cost of 20$ will be added to fixed cost of 3000$.
