4. Kate and Sally went to the mall to shop. Kate bought 2 pairs of shoes and 2 pairs of sunglasses for $36.50. Sally bought 4 pairs of shoes and 1 pair of sunglasses
for $46.75.
In the system of equations below, x represents the cost of a pair of shoes and y
represents the cost of a pair of sunglasses.
2x + 2y = 36.50
4x + y = 46.75 ---> rewrite as y = 46.75 - 4x
What is the value of x, the cost of a pair of shoes?
Show work here: (5 points)

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.

no this is a nonlinear negative
