We are given graph for the Volume of dirt remaining at a construction site.
x axis represents time in hours.
y-axis represents volume in ft^3.
y-intercept is a point on y-axis, where line cut y-axis.
According to graph, line cuts y-axis at 450.
Therefore, y-intercept is 450.
y-intercept represents the initial volume of the dirt.
Therefore, initial volume of the dirt is 450 ft^3.
x-intercept is a point on x-axis, where line cut x-axis.
According to graph, line cuts x-axis at 6.
Therefore, x-intercept is 6.
x-intercept represents the time when dirt has finished.
Therefore, after 6 hours the dirt gets finish.
