Draw the graphs of 
and 
. Determine the coordinates of the vertices of the triangle formed by these lines and x-axis and shade the triangular area. Calculate the area bounded by these lines and x-axis.
and 
Coordinates of the vertices of triangle formed with x-axis
(2, 3), (-1, 0) and (4, 0)
Height of the triangle = 3 units
Base of the triangle = 5 units
Area = 0.5 × base × height = 7.5 sq units
