Re: Coordinate Geometry

Hi,

Neat work!

CG#160. Find the equation of the line on which the length of a perpendicular drawn from origin is 6 and the angle which this perpendicular makes with X-axis is 30°.

Re: Coordinate Geometry

Hi,

 

Excellent!

CG#161. Given that a line S is perpendicular to line 4x - y = 2. Also, the area of the triangle formed by the line S and the co-ordinate axes is 10. Find the equation of the line S.
