Which point is located at (Negative 3.5, Negative 4.5)? On a coordinate plane, point A is 3.5 units to the left and 4.5 units down. Point K is 3.5 units to the right and 4.5 units up. Point R is 3.5 units to the left and 4.5 units up. Point Y is 4.5 units to the left and 3.5 units down. point A point K point R point Y

The relationship is proportional.

Step-by-step explanation:

The cost of 10 pounds of grapes at stall A is $15.

So, the price rate of grapes is dollars per pound.

So, the relation between the weight (w, in pounds) and the price of grapes (c, in dollars) are related as  

c = 1.5w ......... (1)

So, from the above equation, we can say that the relationship is proportional. (Answer)
