A ray of light coming from the point (1, 2) is reflected at a point A on the x–axis and then passes through the point (5, 3). The coordinates of the point A are
(a) (-1/2,1/2) (b) (1,1)(c)(1/2,1) (d) (-1/2,1)

I'm too lazy to do that problem. But all you need to do is calculate the original slope, and use the law of reflection to figure out the other angle.

Start with the point-slope formula.

Hint: The angle of incidence is equal to the angle of reflection.

Notice that NONE of the possible answers are ON the X-axis.

The ray of light is not touching x-axix.
Then how it would be reflected.

Hey it cant be anyone of these.. you said point "A" is on X-Axis.
So the Y co-ordinate should be zero... :)

IT MAKES A TRIANGLE WE HAVE COORDINATES OF TWO POINTS OF THE TRIANGLE
SOLVE FOR THE THIRD
