Distance of a point (2,5) from the line 3x+y+4=0 measured parallal to the line 3x-4y+8=0 is:a. 15/2b. 9/2c. 5d. none

Answer» `3x-4y+8=0`
m=3/4
`(k-5)/(h-2)=3/4`
`4k-20=3h-6`
3h-4k=-14-(1)
3h+k=-4-(2)
Subtracting equation 2 from equation1
k=2
h=-2
PQ=`sqrt((2+2)^2+(5-2)^2)`
PQ=`sqrt(4^2+3^2)`
PQ=`sqrt25`
PQ=5cm
