Use the image to answer the question.

An illustration shows quadrant one of a coordinate plane where the x-axis and y-axis range from 0 to 6 in increments of 1. The y-axis is titled total cost in dollars and the x-axis is titled number of markers. A line is marked on the graph, passing through coordinates left parenthesis 0 comma 0 right parenthesis and left parenthesis 4 comma 3 right parenthesis.

What is the unit cost from the graph?(1 point)

1 answer

To find the unit cost from the graph, we need to determine the slope of the line passing through the given coordinates (0,0) and (4,3).

The formula for slope is:
m = (change in y) / (change in x)

Let's calculate the slope:
m = (3 - 0) / (4 - 0)
m = 3/4

Therefore, the unit cost from the graph is 3/4, or $0.75.
