Pair Of Linear Equations In Two Variables

Question 2:

On comparing the ratios, find out whether the lines representing the following pairs of linear equations at a point, are parallel or coincident:

Answer:

(i) 5x − 4y + 8 = 0

7x + 6y − 9 = 0

Comparing these equations with

and , we obtain

Since ,

Hence, the lines representing the given pair of equations have a unique solution and the pair of lines intersects at exactly one point.

(ii) 9x +...
