A) \[6(x+y)-25=0\]
B) \[2x+6y+1=0\]
C) \[2x+3y-6=0\]
D) \[6(x+y)+25=0\]
Correct Answer: B
Solution :
[b] The equation of the line joining the points (2,-1) and (5,-3) is given by \[y+1=\frac{-1+3}{2-5}(x-2)\] Or \[2x+3y-1=0\] Since \[({{x}_{1}},4)\]and \[(-2,{{y}_{1}})\]lie on \[2x+3y-1=0\], we have \[2{{x}_{1}}+12-1=0\]or \[{{x}_{1}}=-\frac{11}{2}\] And \[-4+3{{y}_{1}}-1=0\]or \[{{y}_{1}}=\frac{5}{3}\] Thus, \[({{x}_{1}},{{y}_{1}})\]satisfies \[2x+6y+1=0\].You need to login to perform this action.
