Find the equation of a line which makes an angle of `135^(@)` with the x-axis and passes through the point (3,5).

Text Solution

Verified by Experts

Here, `m=tan 135^(@)=tan(180^(@)-45^(@))=-tan 45^(@)=-1`
Hence, the required equation is `(y-5)/(x-3)=-1 Leftrightarrow (y-5)=3-x Leftrightarrow x+y-8=0`
