#### Question

Given the linear equation 2x + 3y – 8 = 0, write another linear equation in two variables such that the geometrical representing of the pair so formed is :

(i) intersecting lines

(ii) parallel lines

(iii) coincident lines

#### Solution

1) Given the linear equation are 2x + 3y - 8 = 0

We know that interesting condition

a_1/a_2 != b_1/b_2

Where a_1 = 2, b_1 = 3, c_1 = -8

Hence the equation of other line is  x +2y - 4 = 0

2) We know that parallel line condition is a_1/a_2 = b_1/b_2

Where a_1 = 2, b_1 = 3, c_1 = - 8

Hence the equation is 2x + 6y - 12 = 0

3) We knbow the coincident line condition is a_1/a_2 = b_1/b_2 = c_1/c_2

Where a_1 = 2, b_1 = 3, c= -8`

Hence the equation is  4x + 6y - 16 = 0

Is there an error in this question or solution?
