100 POINTS

Bottles of water sell for $1.50 each.
Graph the relationship between the number of bottles of water sold and the total cost.
(I’m in K12, The total cost goes up to 10/y but it got cut off)

Answer 1

Let bottles be x

• m=1.50

Equation

• y=mx+b
• y=1.5x

Find 2 coordinates

• (0,0)
• (4,6)

Graph attached

Answer 2

Let x = number of bottles sold

Let y = total cost

If bottles of water sell for $1.50 each

Then equation of the line is: y = 1.5x

Coordinates to plot to help draw the line:

(0, 0)

(2, 3)

(4, 6)
