Breyana is buying a new dress. The dress is on sale for 20% off. Breyana will also have
to pay 10% sales tax on the discounted price
of the dress. The expression below
represents the total amount, including the
tax, that Bianca will pay for a dress which
originally costs x dollars.
(x-0.20x) + 0.10(x-0.20x)
What percent of the dress's original price
will Breyana pay?

do you have the measurements?

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.
