1.	If 3x - 5y + 2 = Oand 9x + 3y + a = 0 represents the same straight line, find the value of a and b.
Answer» SOLUTION GIVEN 3x - by + 2 = Oand 9x + 3Y + a = 0 represents the same straight line TO DETERMINE The value of a and b EVALUATION Here it is given that 3x - by + 2 = 0 and 9x + 3y + a = 0 represents the same straight line So by the given CONDITION $\displaystyle \sf{ \frac{3}{9} = \frac{ - b}{3} = \frac{2}{a} }$ Now $\displaystyle \sf{ \frac{3}{9} = \frac{ - b}{3} \: \: \: gives \: }$ $\displaystyle \sf{ \frac{1}{3} = \frac{ - b}{3} \: \: \: \: }$ $\displaystyle \sf{ \implies \: b = - 1 }$ Again $\displaystyle \sf{ \frac{3}{9} = \frac{2}{a} \: \: \: gives}$ $\displaystyle \sf{ \frac{1}{3} = \frac{2}{a} \: \: \: }$ $\displaystyle \sf{ \implies \: a = 6}$ FINAL ANSWER The required value a = 6 , b = - 1 ━━━━━━━━━━━━━━━━ Learn more from Brainly :- 1.
