Which statement describes a unit rate? * 5 points Mary paid $2.50 for 3 bottles of water. Ricardo paid $17.00 for 3 pumpkins. Katherine paid $1.25 for 1 bottle of water. Joshua paid $6.00 for 3 masks.

Step-by-step explanation:

In this context, a unit rate is defined as the amount in dollars paid for one unit of a commodity.

In the given options, all the items are above one except

option C( Katherine paid $1.25 for 1 bottle of water.)

hence all the other amount does not correspond to the unit rate

Mary paid $2.50 for 3 bottles of water. not a aunit rate

Ricardo paid $17.00 for 3 pumpkins.   not a unit rate

Katherine paid $1.25 for 1 bottle of water. a unit rate

Joshua paid $6.00 for 3 masks. not a unit rate

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.
