Question 6 A plumber charges a base fee for all service appointments. If a repair is needed, he adds a charge for each hour of labor. If the total cost, y, in dollars, of the plumber's x-hour repair visit is modeled by
the equation y = 25x + 30, what could the 30 represent?

the 30 is the base number,or where the line begins on the graph

Step-by-step explanation:

It represents the base fee

Step-by-step explanation:

Well we know he charges a flat rate for even making an appointment (probably because he needs to get to a client), and then charges an hourly rate. Thus, anything in his formula that's multiplied by the number of hours must be the hourly rate (25 here) and whatever is constant must be the base fee (30 here).

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
