How do you find the equation of the line t hat is perpendicular to x - 2y = -10 and passes through the point ( -1 , -3 )?
Consider the following Results :
If we use these Results, we can immediately write the eqn. of reqd.
But, for the help of these Results, we can derive the eqn. as under :
Eqn. of the given line
So, the slope of this line is
to given line) must be
Hence, by the Slope-Pt. Form of line, the eqn. of reqd. line is,
