Question

plzz answer this friends. how to find foot of perpendicular from a point to a line.plzz answer it's urgent!! don't see it from Google Please​

Answer 1

Answer:

1. at first draw perpendicular from point on the line
2. write direction cosine of line on which perpendicular is drawn
3. get the coordinates of the point on the line
4. now use perpendicular condition for d.cs to get the coordinates
5. at last put the value in the place of x and y and z

hint; condition for perpendicularity is a1a2+b1b2+c1c2=0

hope it helps any confusion please do tell

Answer 2

Answer:

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.
