Solve the following pair of linear equations by graphical method and find the coordinates of these points where the lines represented by these intersect the y – axis.

3x + 2y = 12;

5x – 2y = 4

To plot the given pair of linear equations, we substitute x = 0 or y = 0

in the given linear equations to get x and y. To find more points on the

lines, take different values of x related to it and we get different values

for y from the equation.

We get the following tables for the given linear equations.

For 3x + 2y = 12

2y = 12 – 3x

For 5x – 2y = 4

2y = 5x – 4

The coordinates of the points where the lines represented by these intersect the y – axis are:

i. (0,6)

ii. (0, – 2)
