You can put this solution on YOUR website! Data
1) 8x = 2y +18,,,,,,,,,,y=4x -9
,,,3y = 12x -12,,,,,,,,,y=4x -4,,,,,lines are parallel,,,,no solution
.
2) 3x-3y= -2,,,,,,,,,,,,y=x+2/3
,,,x-y=5,,,,,,,,,,,,,,,,y=x-5,,,,,,,lines are parallel,,,,no solution
.
3) 2x-3y =-4,,,,,,,,,,,,y=2/3 x +4/3
,,,2x-y =4,,,,,,,,,,,,,,y= 2x-4,,,,,lines are intersecting,,,,one solution(4,4)
.
4) x-y =2,,,,,,,,,,,,,,,y=x-2
,,,x+y =4,,,,,,,,,,,,,,,y= -x+4,,,,,lines are intersecting,,,,one solution(3,1)
