Question

1. Heather is a software saleswoman. Her monthly salary is $1800 plus an additional $50 for every copy of English is Fun she sells.

Let S represent her total salary this month (in dollars), and let N represent the number of copies of English is Fun she sells. Write an equation relating S to N, and then graph your equation using your axes below.

Answer 1

The Total salary S = 1800 + 50 N

Rewriting the equation becomes, S= 50N + 1800 which is analogus to the equation of the st line y =mx +C

 

The plot of S vs N will be a straight line with a slope of 50 and an y- intercept  of $ 1800.
