Determine the intercepts of the line.

y- intercept (_,_)
x- intercept (_,_)

Therefore, the y-intercept is (0,2.5) and x-intercept is (3.5,0) .

Step-by-step explanation:

Intercept means the line touching the axis. As you look at the graph, y-intercept (line touching y-axis) is (0,2.5) and the x-intercept is (3.5,0) .

Take note :

When finding y-intercept, x-coordinate must be 0.

When finding x-intercept, y-coordinate must be 0.

this is answer of 144 cubic meters
