Find a point first on the line 
$$y=x+2$$
The most easiest point is either the x or y intercept.

anonymous · Answer

Let's just pick the x intercept. That means you just let x=0 and then you can find the y-coordinate for the x-intercept.
So the x-intercept would be the point (0, y-coordinate)

anonymous · Answer

y = -x + k. k can be any value. If we have to find the line perpendicular to y=x+2 and passing through some point then we can easily solve k.

anonymous · Answer

so whats our anwer then

anonymous · Answer

y = -x + k. for each k one line will exist. So there are infinite number of parallel lines exist those are perpendicular to 
y = x+2

@sriramreddy please show her how to do it by herself and restrain yourself from giving the answer away until she knows how to do it.
