19. The point on the parabola y2 = 64x which is nearest to the line 4x + 3y + 35 = 0 has coordinates

(A) (9, –24)

(C) (4, –16)

(D) (–9, –24)

Ans : (A)

Sol:

The coordinate of foot of the normal are (am2, –2am)

Comparing the equation of parabola with the standard equation of parabola, we get:

a = 16

We have the equation of line:

4x + 3y + 35 = 0

So, the slope of line is -4/3

So, the slope of normal to the line is 3/4.

So, the point on the parabola is (9, –24).
