If the point P(4, –2) is the one end of the focal chord PQ of the parabola y^(2) = x, then the slope of the tangent at Q is |
|
Answer» `-1//4` Its slope is `-1/4` Therefore the slope of the perpendicular line is 4. Since the tangents at the end of FOCAL chord of a PARABOLA are at RIGHT angle, the slope of the tangent at Q is 4. Hence, (C) is the correct answer. |
