A tangent is drawn to the parabola y2 = 6x which is perpendicular to the line 2x + y = 1. Which of the following points does NOT lie on it?
Solution
Equation of tangent : $y = mx + {3 \over {2m}}$<br><br>${m_T} = {1 \over 2}$ ($\because$ perpendicular to line $2x + y = 1$)<br><br>$\therefore$ tangent is : $y = {x \over 2} + 3$<br><br>$\Rightarrow x - 2y + 6 = 0$
