A) \[x+4y=13\]and \[y=4x-7\]
B) \[4x+y=13\]and \[4y=x-7\]
C) \[4x+y=13\]and \[y=4x-7\]
D) \[y-4x=13\]and \[y+4x=7\]
Correct Answer: C
Solution :
Equation of diagonal \[{{d}_{1}}\] is \[y-1=\frac{5-1}{3-2}(x-2)\] \[\Rightarrow y-1=\frac{4}{1}(x-2)\]\[\Rightarrow y=4x-7\] Equation of diagonal\[{{d}_{2}}\]is \[y-1=\frac{5-1}{2-3}(x-3)\] \[\Rightarrow y-1=-4(x-3)\Rightarrow 4x+y=13\] So equations are, \[4x+y=13\]and \[y=4x-7\].You need to login to perform this action.
