Ex 3.2, 7 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. x – y + 1 = 0 3x + 2y– 12 = 0 Solving (1) x – y + 1 = 0 y = x + 1 Solving (2) 3x + 2y – 12 = 0 2y = 12 − 3x y = (12 − 3𝑥)/2
