Question 619459: write the euation of a line that passes through the giving point and is perpendicular ro the given line. write the equation in the form Ax+By=C where A,B,C are integers and A>0.
(4,7) y=x-3. i dont have a cue to this problem.

You can put this solution on YOUR website!
The given line is y=x-3 which is also y=1x-3

The slope of this given line is 1

So the perpendicular slope is -1 (flip the fraction and change the sign)

So we must find an equation of a line that has a slope of -1 and passes through (4,7)

Can you take it from here?
