Tom starts lawn mowing business before he can begin he purchases a new lawnmower each weekend he mows the same number of lawns and earns the same amount of money write and equation to show how much money he's earned any week

B. y = 60x - 150

Step-by-step explanation:

From week 1 to week 2 he earn -30 - (-90) = $60

From week 2 to week 3 he earn 30 - (-30) = $60

This profit is repeated every week, and 60 represent the slope of the line that relates y and x.

Then, the y value for week 0 is -150, in this way:

From week 0 to week 1 he earn -90 - (-150) = $60

the same value as before is satisfied. -150 is the y-intercept of the line (the y value when x = 0). Therefore, the equation is:

y = slope*x + y-intercept = 60x - 150
