00:02 Q2. On comparing the ratios a1/b1 , a2/b2 and a3/b3 , find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincident:
18:52 (i) 5 x – 4 y + 8 = 0 ; 7 x + 6 y – 9 = 0
(ii) 9x + 3 y + 12 = 0 ; 18 x + 6 y + 24 = 0
(iii) 6 x – 3 y + 10 = 0 2 x – y + 9 = 0
00:40 Procedure to find the ratios
01:21 ratio of coefficients of x
01:29 ratio of coefficients of y
01:36 ratio of constant terms
relate relationship of ratios and their graphical representation
a1/b1 , a2/b2 and c1/c2
01:56 a1/b1 is not equal to a2/b2.graphical representation of system of linear equation is intersecting
relate relationship of ratios and their graphical representation
a1/b1 , a2/b2 and c1/c2
02:57 (ii) 9x + 3 y + 12 = 0 ; 18 x + 6 y + 24 = 0
03:38 Find ratio of coefficients of x
03:45 Find ratio of coefficients of y
03:56 Find ratio of constant terms
04:06 relate the above ratio.
04:32 relate relationship of ratios and their graphical representation.
a1/b1 = a2/b2 = c1/c2
04:46 (iii) 6 x – 3 y + 10 = 0 2 x – y + 9 = 0
05:28 Find the ratio a1/b1 , a2/b2 and c1/c2
05:56 Find the relation between these ratios
06:07 Relate relationship of ratios and their graphical representation
