Question

Bottles of water sell for $1.50 eachGraph the relationship between the number of bottles of water sold and the total cost Proportional relationships

Answer 1

The function that we have to draw is:

`y\text{ = 1.5x}`

y is the total cost. x is the number of bottles of water sold. I attach a picture of the graph. But before that, let's find some points to put in the graph. I will get two points, when x = 0 and when x = 1:

`y\text{ = 1.5}*0=0`

`y\text{ = 1.5}*2=3`

Thus the points will be A = (0,0) and B = (2,3). Then the graph will be:
