The length of perpendicular from (3,1) to line 4x + 3y + 20 = 0 is.
A straight line makes angle 135o with x - axis and cut y - axis at distance -5 from origin.The equation of line is.
2x + y + 5 = 0
x + 2y + 3 = 0
x + y + 5 = 0
x + y + z = 0

The equation of lines passing through (3,2) and perpendicular to y = x is.
x - y = 5
x + y = 5
x - y =1
If P is the length of perpendicular from origin to the line which intercepts a and b on axes , then.
a2 + b2 = p2
a2 + b2 = 1/p2
1/a2 + 1/b2 = 2/p2
1/a2 + 1/b2 = 1/p2
If x1,x2,x3 and y1,y2,y3, are in G.P .Where common ratio is r,then point P (x1,y1), Q (x2,y2), R (x3,y3) are on.
