A) \[7x+2y=11;y-2x=3\]
B) \[2x+7y=11;\,5x+\frac{35}{2}y=25\]
C) \[3x-7y=10\,;8y-6x=4\]
D) \[3x-4y=1\,;8y-6x=4\]
Correct Answer: D
Solution :
Equations of lines passing from\[(-2,\,\,-1),\,\,(2,\,\,2)\]and\[(-1,\,\,-1),\,\,(3,\,\,2)\]are respectively \[y-2=\frac{2-(-1)}{2-(-2)}(x-2)=\frac{3}{4}x(x-2)\] and \[y-2=\frac{2-(-1)(x-3)}{3-(-1)}=\frac{3}{4}(x-3)\] or \[4y-8=3x-6\]and\[4y-8=3x-9\] or \[4y-3x=2\]and\[3x-4y=1\] or \[8y-6x=4\]and\[3x-4y=1\]You need to login to perform this action.
