Answer 1

We are given that cost of 10 cookies = $5.

Let us find the cost of one cookie.

Cost of one cookie = 5/10 = $0.5.

Let us assume number of cookies purchased = x cookies.

And total cost of x number of cookies = y.

Therefore,

Cost of x cookies at the rate $0.5 each cookie = 0.5x

Therefore, cost equation would be

y=0.5x.

For 0 number of cookies there would be 0 cost.

So, first coordinate would be (0,0) and we are given 10 cookies cost = $5.00.

Therefore, second coordinate would be (10,5).

Plotting (0,0) and (10,5) coordinates on the graph and jointing the points to draw a line.

The drawn line represents the proportional relationship.
