Question -

Draw the graphs of the following linear equation on the same graph paper.
2x + 3y = 12, x -y = 1
Find the co-ordinates of the vertices of the triangle formed by the two straight lines and the y-axis. Also find the area of the triangle.



Answer -


Now plot the points (6, 0) (0, 4) on the graph to get a line.
Now plot the points (1, 0) and (2, 1) on the graph to get another line.
Area of the triangle FEB so formed,
=  FB x FL = x 5 x 3
= 15/2
= 7.5 sq. units
co-ordinates of E, F, B are E (3, 2), (0, -1) and (0, 4)
