Question

What is the equation of the chord of the circle x^2+y^2=16, passing through (2,3).

Pls help!

Answer 1

If lines 7x-2y+10=0 and 7x+2y-10=0 forms an isoceles triangle with the line y=2. Then what is the area of the triangle.

Pls help

Answer 2

There are infinitely many chords passing through any point within the circle. Two such chords, easy to describe are
x=2 and y=3.
----------------------------------------
Clearly, the vertex of the triangle is at (0,5), so the altitude is 3.

The base of the triangle goes between (-6/7,2) and (6/7,2), so it has a length of 12/7.

Now you can get the area...
