Pair Of Linear Equations In Two Variables
Question
Given the linear equations 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
We have,
2x + 3y - 8 = 0
(i) Another linear equation in two variables such that the geometrical representation of the pair so formed is intersecting lines is
3x - 2y - 8 = 0
(ii) Another parallel lines to above line is
4x + 6y - 22 = 0
(iii) Another coincident line to above line is
6x + 9y-24 = 0. Ans.
