Question

Perpendicular distance from origin to the line 3x+4y−12=0 is​

Answer 1

Answer:

12/5

Step-by-step explanation:

We Know That ,

Perpendicular Distance From a point (x1 , y1)  + 0

Here,

(x1 , y1) = (0,0)

ax + by + c = 3x + 4y - 12

So,

Perpendicular Distance = 3(0)+4(0) - 12/√3^2+4^2

= 0 + 0 - 12 /√9+16

= -12/√25 = 12/5 units
