Will mark brainliesttimothy bought 10 cookies for $5.00 let x represent the number of cookies purchased, and let y represent the total cost graph the line that represents the proportionat relationship.

The line should go from (0,0) to (7,3.5)

The equation is Y = X(0.5)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
