Answer» The given equations is\xa0x+3y=6.......(i)\xa02x-3y=12....(ii)\xa0Now, from equation (i)If x= 0, then\xa00+3y=63y=6y=6/3y=2\xa0(x,y) =(0,2)...(I)and when y=0 , then\xa0x+0=6x=6\xa0(x,y) =(6,0)........(II)\xa0Now,from equation (ii),If x= 0, then\xa00-3y=12y=-4(x,y)=(0,-4)...............(III)and\xa0if y=02x-0=12x=6(x,y) = (6,0)............(IV)\xa0Mark these points (I), (II) , (III) & (IV) on graph as shown below:\xa0thus, x\xa0+ 3y\xa0= 6 intersects\xa0y–axis at (0, 2) and\xa0\xa02x\xa0– 3y\xa0= 12 intersects\xa0y–axis at (0, – 4). Cause it gives detailed answer Refer google mohit☺ |
