Respuesta :
draw a graph with number of bottles on the x axis ( and number it 1 through 10 )
put price on the y axis and label it in increments of $1.50 ( 1.50, 3.00 , 4.50, 6.00, etc.
Then put dots on the intersection of price with the number of bottles and then draw a straight line through the dots.
for every 1 bottle of water sold the price increases by 1.50
so at x 1 y = 1.50
at x 2 y = 3.00
at x 3 y = 4.50
and so on

We want to graph a linear equation that represents the cost of buying x bottles of water.
The graph can be seen at the end of the answer.
To get the graph, we first must find the equation that we want to graph.
We know that each bottle costs $1.50, so if you buy x bottles, you must pay $1.50 x times, then the cost function is:
c(x) = $1.50*x
Now to graph this line, we need to find two points that are on the line and then connect them with a line, to get the points we just need to evaluate the function in two different values of x.
We can use
x = 0
c(0) = $1.50*0 = $0
x = 1
c(1) = $1.50*1 = $1.50
then we have the points (0, $0) and (1, $1,50).
We need to find these in the coordinate axis, and then draw a line that connects them. The graph can be seen below.
