Question

The slope of the tangent to the curve x= t²+3t-8, y=2t²-2t-5 at the point (2, −1) is

(A)  22/7   (B)   6/7   (C) 7/6  (D)  -6/7

Answer 1

The given point is (2, −1).

At x = 2, we have:

The common value of t is 2.
Hence, the slope of the tangent to the given curve at point (2, −1) is

The correct answer is B.
