Draw the graphs of the equations x – y + 1 = 0 and 3x + 2y – 12 = 0

Question.

Draw the graphs of the equations x – y + 1 = 0 and 3x + 2y – 12 = 0. Determine the coordinates of the vertices of the triangle formed by these lines and the x-axis, and shade the triangular region.


Solution:

x – y + 1 = 0 ...(i)

Draw

3x + 2y – 12 = 0 ...(ii)

Draw the

Draw the graphs

The vertices of the triangle are

A (2, 3), B (–1, 0) and C (4, 0)
