Answer» Answerx+3=0..(i)x=−3The graph of x=−3 will be a LINE passing through x=−3 parallel to Yaxis.y−2=0 ..(ii)y=2The graph of y=2 will be a line passing through y=2 parallel to X axis.2x+3y=12 …(iii)3y=12−2xy=(12−2x)/3When x=0,y=(12−2×0)/3=12/3=4When x=3,y=(12−2×3)/3=(12−6)/3=6/3=2When x=6,y=(12−2×6)/3=(12−12)/3=0x= 0 ,3 ,6Y= 4 ,2 ,0Mark the above points on graph. JOIN them.From the graph, it is clear that the vertices of the triangle formed by the LINES are A(−3,2),B(−3,6) and C(3,2). |
