Most would find it helpful to change the equation to standard form, which is y=mx + b, where m=the slope of the equation and b=the equation's y intercept.
Let's convert 3x-y=6 to standard form by using some algebraic manipulation:
3x - y = 6
3x = 6 + y
3x - 6 = y
y = 3x - 6
Now we know that the slope of this line is 3 and that the y-intercept of this line is -6. To graph, make a point at -6 on the y axis.
Use the slope (rise over run) to make a couple more points, then connect them to make the graph of the line.

That equals 2xy + 3y which factors to y(2x + 3)
No translation will invert a quadratic graph.
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
y=-10x-4
