Q.

A rectangle is formed by the lines x=0, y=0, x=3, and y=4. Let the line L be perpendicular to 3x+y+6=0 and divide the area of the rectangle into two equal parts. Then the distance of the point (12,-5) from the line L is equal to:                [2026]

1 10  
2 25  
3 210  
4 310  

Ans.

(3)

Line is y=x3+C

Line passes thru (32,2)

2=12+CC=32

y=x3+32

6y=2x+9

Line is 2x-6y+9=0

Dist=|1+30+940|=40=210
