Help!!! Just this 1 problem
find the equations of two lines through A, one parallel and the other perpendicular to the line defined by the given equation:
30.)
thats all for today
thank you very much for all your helps!
Rewrite in standard form: so the slope of lines parallel to this all have slope , and the slope of a line perpendicular to this has slope .
Now the equation of the parallel line is:
now it goes through , so
so , so:
.
A similar procedure gives the line at right angle to this one as:
