If the point P(2, –2) is the one end of the focal chord PQ of the parabola y 2 = 2x then slope of the tangent at Q is
Text Solution
Verified by ExpertsThe correct answer is:
B
Equation of tangent at (2, –2)
y (–2) = x + 2
–2y = x + 2
2y + x + 2 = 0
m = – 1/2
m ′ = (slope at Q) = 2
mm ′ = –1 (due to focal chord)
