3x+2y=4

9x+6y=12

for first equation:

3x+2y = 4

put x = 0

3(0)+2y=4

2y=4

y=2

put x= 2

3(2)+2y=4

6+2y=4

2y=-2

y=-1

put x= 4

3(4)+2y=4

12+2y = 4

2y= -8

y= -4

similarly put the values of x in second equation also:

You will get the three values of x and y.

Put the values of first and second equation in the graph.

you will observe the line!!!!
