The x-axis on a graph represents the number of identical items purchased. the y-axis presents the total cost in dollars. what does the slope of the graph represent? 1. the number of items per dollar 2. the total cost for all the items 3. the unit cost per item 4. the total number of items bought

3. The unit cost per item

Step-by-step explanation:

We are given,

The x-axis represents the number of identical items and y-axis represents the total cost in dollars.

Since, the slope of a graph is equal to the change in y-coordinates by change in the x-coordinates.

i.e. Slope is given as the change in the total cost by the change in the number of items purchased.

i.e. Slope represents the cost of an item in dollars.

Thus, it gives that the slope is the cost per item in dollars.

Hence, option 3 is correct.

the unit cost per item.
