Draw the graphs of the equations x - y + 1 = 0) and 3x + 2y - 12 = 0. Determine thecoordinates of the vertices of the triangle formed by these lines and the x-axis, andshade the triangular region. *also find area of triangle* |

Answer» Answer: x−y+1=0....(1) 3x+2y−12=0....(2) put x=0 in (1) 0−y+1=0⇒y=1 (0,1).....(a) put y=0 in (2) 3x+2(0)−12=0→x=4 (4,0).....(b) put x=0 in (2) 3(0)+2y−12=0→y=6 (0,6)......(C) put y=0 in (1) x−0+1=0⇒x=−1 (−1,0)...(d) From FIGURE, the vertices of triangle are (−1,0),(2,3),(4,0) |
