The length of the perpendicular from to the line is
- A units
- B units
- C units
- D units
Answer & Solution
Correct Answer
(B) units
Step-by-step Solution
Detailed explanation
As we know length of the perpendicular from x1,y1,z1 to the line ax+by+c=0 is d=ax1+by1+ca2+b2 Length of the perpendicular from1,-2 to the line 12x+5y+63=0 is d=121+5-2+63122+52 ⇒d=12-10+63144+25=6513=5 units.
