Q2 of 29 Page 3

find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincide:

5x – 4y + 8 = 0


7x + 6y – 9 = 0

5x – 4y + 8 = 0


7x + 6y – 9 = 0


Here a1 = 5, a2 = 7


b1 = –4, b2 = 6


c1= 8, c2 = –9


Now,





Here


The lines intersect.
