A) \[y=3,\ x+y=5\]
B) \[y=-3,\ x-y=5\]
C) \[y=4,\ x+y=3\]
D) \[y=-4,\ x-y=3\]
Correct Answer: A
Solution :
The tangent will be \[y-3=m(x-2)\] Þ \[y-mx=3-2m.\] But it is tangent to the given ellipse, therefore\[m=0,\,-1\]. Hence tangents are \[y=3\]and\[x+y=5\].You need to login to perform this action.
