## Question

### Solution

Correct option is

4x = 9y2 – 12y + 8

be the end points of chord AB.

Also let M ≡ (x1y1) be a point which divides AB internally in ratio 1: 2.

It is given that slope of PQ = 2.

As M divides PQ in 1 : 2 ratio, we get:

we have t eliminate two variables t1 and t2 between (i), (ii) and (iii).

From (i), put t2 = 1 – tin (iii) to get:

On substituting the values of t1 and t2 in (ii), we get:

Replacing x1 by x and y, we get the required locus as:

4x = 9y2 – 12y + 8

Also let M ≡ (x1y1) be a point which divides AB internally in ratio 1: 2.

It is given that slope of PQ = 2.

As M divides PQ in 1 : 2 ratio, we get:
