Answer by venugopalramana(3286) (Show Source): You can put this solution on YOUR website!
there is a formula for distance of a point (h,k) from a line given by the equation
a*x+b*y+c=0...the formula is
distance =
That is ,just substiute the given coordinates of the point (h,k)for x and y in the given equation of the line and devide it by
for the given problem we have line as 2x+y-2=0 and point as (-3,4).So a=2;b=1;c=-2;h=-3;k=4.
distance = =-4/
