When lisa started at her current job, her employer gave her two days of paid vacation with a promise of three additional paid vacation days for each year she remains with the company to maximum of four work weeks of paid vacation. Let x represent the number of years she has worked for this employer and y represent the number of paid vacation days she has earned.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

what is the original number? you forgot to add it.

a. is correct
