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)

Answer 1

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.
