1.1 – N – Analytical Geometry Exercise Problems With Solutions

Part – A 1.  Find the perpendicular distance from the point (3, -5) to the straight line 3x-4y-26=0. Soln: W.K.T  The length of the perpendicular distance from (x1,y1) to the line ax + by + c = 0  is ±  (ax1 + by1 + c)/ √(a2 + b2 ) Given straight line is     3x-4y-26 =0 Given point (x1,y1)  =  (3, -5) i.e  ±  3(3) – 4(-5) – 26/ √(32 + (-4)2 )   =   3 / 5 2.     Find the distance between the line 3x+4y = 9 and 6x+8y = 15. Soln: W.K.T …
