bottles of water sell for $1.50 each. graph the relationship between the number of bottles of water sold and…

Explanation:

Step1: Define variables

Let $x$ be the number of bottles of water sold and $y$ be the total cost. The cost - per - bottle is $1.50$, so the relationship is $y = 1.5x$.

Step2: Find points to plot

When $x = 0$, $y=1.5\times0 = 0$. When $x = 1$, $y = 1.5\times1=1.5$. When $x = 2$, $y=1.5\times2 = 3$.

Step3: Plot the points

Plot the points $(0,0)$, $(1,1.5)$, $(2,3)$ on a coordinate - plane. The $x$ - axis represents the number of bottles of water sold and the $y$ - axis represents the total cost. Then draw a straight line through these points since the relationship is linear.

Answer:

Plot the points $(0,0)$, $(1,1.5)$, $(2,3)$ and draw a straight line through them with the $x$ - axis for the number of bottles and the $y$ - axis for the total cost.
