(i) The given equation is 3x + 2y – 12 = 0.
It can be written as

This equation is of the form, x/a + y/b=1
where a = 4 and b = 6.
(ii) The given equation is 4x – 3y = 6.
It can be written as

The equation is of the form, x/a + y/b =1 , where a = 0 and b = -2/3
Therefore, equation (3) is in the intercept form, where the intercept on the y-axis -2/3 is and it has no intercept on the x-axis.
