- Q.5 (i) Draw the graphs representing the equation 2x = y + 2 and 4x + 3y = 24 on the same graph paper. Find the area of the triangle formed by these lines and the X-axis. Answer: Area = 10 square units 2x = y + 2, i.e. y = 2x – 2: points (1, 0), (0, –2), (3, 4). 4x + 3y = 24: points (6, 0), (0, 8), (3, 4). Plo... 1
