Questions
Slope of a line is 1. The points on the line at a distance of 2 units from the point which lies on the line are
detailed solution
Correct option is A
The inclination of the line L is θ=tan−1(1)=π4 The coordinates of a point on the line L at a distance of r units from x1,y1 are x=x1±rcosθ and y=y1±rsinθ, here θ is inclination of the line θx=x1±rcosθ and y=y1±rsinθ, here θ is inclination of the line θHence the required coordinates are x=x1±rcosθ=32±212=32±2=42,22and y=y1±rsinθ=32±212=32±2=42,22 Therefore, the required points are (42,42)=(22,22)Talk to our academic expert!
