Question

The cost of a service call to fix a washing machine can be expressed by the linear function Y 43X* 33, where y represents the total cost and x represents the number of hours it takes to fix the machine. What does the y-intercept represent?​

Answer 1

The y-intercept of the linear function represents the fixed cost associated with the service call that is not dependent on the time taken to fix the machine.

Step-by-step explanation:

The y-intercept of a linear function represents the starting point or initial value of the dependent variable. In this case, the y-intercept of the function Y = 43X + 33 represents the total cost of the service call when the number of hours it takes to fix the machine is zero. It is the fixed cost associated with the service call that is not dependent on the time taken to fix the machine.
