Question -
Answer -
(i) 3x – 4y = 7
3x = 7 + 4y
x =
Substituting some different values of y, we get their corresponding values of x as shown below
Plot these points on the graph and join them. Similarly in the equation
5x + 2y = 3
=> 5x = 3 – 2y
x =
Plot these points and join them We see that the lines intersect each other at (1, -1)
x = 1, y = -1
Now the region between the these lines and y-axis has been shaded as shown
(ii) 4x – y = 4
3x + 2y = 14
4x – y = 4
y = 4x – 4
Substituting some different values of x, we get their corresponding values of y as given below
Plot these points and join them Similarly in equation
3x + 2y = 14
3x = 14 – 2y
x =
Now plot these points and join them
We see that these lines intersect each other at (2, 4)
x = 2, y = 4
The region between these two lines and y-axis has been shaded as shown
