Answer:
Below are selected answers which are correct
10 lb of apples will cost Zack $4.
1 lb of apples will cost Zack $2.50.
Explanation:
Given:
Graph titled is Cost of Apples.
The cost of apples is proportional to the weight of the apples in pounds as shown on the graph.
Here the horizontal axis
is labelled in cost in dollars.
And vertical axis
is labelled weight in pounds,
Both axis range are from (0-10) with and increment of 0.5
The points given are (1,2.5) and (4,10),
from above points we get can say the equation will become;
![y=2.5x](https://img.qammunity.org/2020/formulas/mathematics/high-school/3as4gbhlx0gzi3iw1rcmuhcpai6wanylva.png)
when x = 1 y= 2.5 and when x=4 y = 10.
Hence we can say that,
10 lb of apples will cost Zack $4.
1 lb of apples will cost Zack $2.50.
