The perpendicular distance from (1,2) to the straight line 12x+5y=7 is
15/13
12/13
5/13
7/13
Perpendicular distance from (x1,y1) to the line ax+by+c=0 is |ax1+by1+c|√(a)2+b2
∴ perpendicular distance from (1,2) to the line 12x+5y=7 is = |12+10−7|√(12)2+52=1513
The equation of the straight line passing through the point of intersection of lines 3x – 4y – 7 = 0 and 12x – 5y – 13 = 0 and perpendicular to the line 2x – 3y + 5 = 0 is
