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.
<em>y-intercept is a point on y-axis, where line cut y-axis.</em>
According to graph, line cuts y-axis at 450.
<h3>Therefore, y-intercept is 450.</h3>
<h3><em>y-intercept represents the initial volume of the dirt.</em></h3>
<em>Therefore, initial volume of the dirt is 450 ft^3.</em>
x-intercept is a point on x-axis, where line cut x-axis.
According to graph, line cuts x-axis at 6.
<h3>Therefore, x-intercept is 6.</h3><h3><em>x-intercept represents the time when dirt has finished.</em></h3>
<em>Therefore, after 6 hours the dirt gets finish.</em>
