Question 2 (i) On comparing the ratios a1a2 , b1b2 and c1c2 , find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincident. 5x - 4y + 8 = 0 7x + 6y - 9 = 0
On comparing the ratios a1a2,b1b2 and c1c2, and without drawing them, find out whether the lines representing the following pairs of linear equation intersect at a point, are parallel or coincide:
(i) 5x−4y+8=0
7x+6y−9=0
(ii) 9x+3y+12=0
18x+6y+24=0
(iii) 6x−3y+10=0
2x−y+9=0
