The x-axis on a graph represents the number of identical items purchased. the y-axis represents the total cost in dollars. what does the slope of the graph represent? the unit cost per itemthe number of items per dollar the total cost for all the itemsthe total number of items bought

the unit cost per item

Step-by-step explanation:

The description of the graph tells you what the slope means. The slope is the (change in) y-value (cost) per (change in) x-value (item), thus is cost per item.

The slope of the line from the origin to a point is the average cost for that number of items. The slope of a tangent line at a point on the curve is the marginal cost for that number of items.

When the curve is linear and goes through the origin, the slope is the same everywhere and is the cost per item. (It is also the average cost and the marginal cost, where that is of interest.)

d 600 because 15*10*2=300

300+300=600
