Draw the graphs of the equations 
. Determine the coordinates of the vertices of the triangle formed by these lines and y-axis. Calculate the area of the triangle so formed.
Coordinates of the vertices of the triangle formed by these lines and y-axis
(1, 0), (0, -3), (0, -5)
Height of triangle = 1 unit
Base of triangle = 5 – 3 = 2 unit
Area of triangle = 0.5 × 1 × 2 = 1 sq. units
