Given:
The graph shows the relationship between the number of pounds of apples purchased and the total cost of the apples.
To find:
The cost of 1 pound of apples.
Solution:
We need to find the slope of the line to get the cost of 1 pound of apples.
From the given graph it is clear that the line passes through two points (0,0) and (2,3). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-0}{2-0}[/tex]
[tex]m=\dfrac{3}{2}[/tex]
[tex]m=1.5[/tex]
Therefore, the cost of 1 pound of apples is $1.5.
