<span><span><u>Answer</u>
8 lemons
</span><u>Explanation</u><span>
If 2 lemons cost 15 cents, then 1 lemon would cost;
15÷2=7.5 cents.
To get the number of lemons that can be bought we you divide 60 by the cost on one lemon.
That is;
60÷7.5=8 lemons.

Hi there Mary Dominguez, So what a vertical line test down is to find out if a particular graph is a function or not. What you do is take a vertical strait line and move it right to left or left to right, depending on your preference, along the X axis. The reason this works is a function can not have an x that has 2 different y values. If we use the vertical line test on a graph with say a graph that has (2,3) and (2,4) we can use the vertical line test and see that the line hits 2 points at once which means its not a function :)
