Question

Select the correct text in the table.

Answer 1

Answer:

rate of change: the amount the charges increase for  each additional hour of work

y-intercept: the average cost of parts for each visit

Step-by-step explanation:

In the context of the problem, x-variable represents Number of Hours and y-variable represents Total Charge. The rate of change represents how much y varies for an unit variation in x. For this problem, that means how much the cost increase when 1 more hour of work is done. The y-intercept is the value of y when x = 0. For this problem, that means how much cost is charged when zero hours are worked. Given that Mark charges his customers for the parts required to make repairs and a certain amount per hour, the y-intercept represents the average cost of the parts required.

Answer 2

Rate of change : the amount the charges increase for  each additional hour of work

Intercept : The average cost of parts for each visit

Step-by-step explanation:

The equation that models the situation is given as;

y = 51.25x + 32.96 where x is the time spent making repairs and y is the total amount charged on a customer after a repair.

From the graph, the slope represents the amount the charges increases with additional hours of time repair.

The y-intercept is where, x=0, y=32.96, which means its the minimum cost charged for a repair in every visit is $32.96.Then additional costs will increase due to more time spent as a product of the slope in the equation.
