The foot of the perpendicular drawn from the origin, on the line, is P. If the line meets x-axis at A and y-axis at B, then the ratio BP : PA is :
1 : 3
3 : 1
1 : 9
9 : 1
As we learned,
Selection formula -
- wherein
If P(x,y) divides the line joining A(x1,y1) and B(x2,y2) in ration
and
Slope – point from of a straight line -
- wherein
slope
point through which line passes
and
y - 0 =
3y = x
and 3x + y =
3(3y)+ =
y =
Option 1)
