Ex 3.1, 2 On comparing the ratios ๐1/๐2 , ๐1/๐2 & ๐1/๐2 , find out whether the lines representing the following pair of linear equations intersect at a point, parallel or coincident (ii) 9x + 3y + 12 = 0 ; 18x + 6y + 24= 0 9x + 3y + 12 = 0 18x + 6y + 24 = 0 9x + 3y + 12 = 0 Comparing with a1x + b1y + c1 = 0 โด a1 = 9 , b1 = 3 , c1 = 12 18x + 6y + 24 = 0 Comparing with a2x + b2y + c2 = 0 โด a2 = 18 , b2 = 6 , c2 = 24 โด a1 = 9 , b1 = 3 , c1 = 12 & a2 = 18 , b2 = 6 , c2 = 24 Since ๐1/๐2 = ๐1/๐2 = ๐1/๐2 So, we have infinite solutions Therefore, the lines that represent the linear equations are coincident
