A painter is paid 8 dollars per hour and can paint 8 m2 with a roller in this time. Renting a spray gun costs 5 dollars for each hour of use (spraying and cleanup), and the painter can paint 20 m2 per hour with the spray gun. It takes 1/2 an hour for the painter to clean up after using the roller, but 1 hour using the spray gun. You must pay the painter for her time and you must also pay for renting the spray gun for the total amount of time (including cleanup) the spray gun was needed. How much money do you save by using the spray gun on a paint job that involves painting 40 m2.

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
