Anna's birthday party costs $1, plus an additional $2 for each guest she invites. Write an equation that shows the relationship between the guests x and the cost y. Write your answer as an equation with y first, followed by an equals sign.

y = $1 + $2x

Step-by-step explanation:

The one dollar represents the amount of the party alone. The two dollars multiplied by the x gets you how much money will be spent towards guests altogether. Adding these gets you the total cost. (FYI - I put the dollar sign, but you may not need it.)

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.

answer: 1 and 3
