Question

b.
2.
On comparing the ratios and find out whether the lines representing the
following pairs of linear equations intersect at a point, are parallel or coincident
I) 5x-4y+8=0
7x+6y-9=0​

Answer 1

Answer:

If both the lines intersect at a point, then there exists a unique solution to the pair of linear equations. ... If a1 / a2 ≠ b1 / b2 then, the pair of linear equations is consistent. 2. If a1 / a2 = b1 / b2 = c1 / c2 , then the pair of lines are coincident and the pair of equations is dependent and consistent.
