Here is shown two things but not the answers to your questions.

If the slopes of each of two lines in a plane are m and M, and if the m%2AM=-1, then the two lines are perpendicular. In other words, if the slopes are negative reciprocals of each other, then the lines are perpendicular.

Slope-Intercept form equation for a line is often represented y=mx+b.
The variable m is the slope.

A standard form equation of a line as Ax+By=C, can be solved for y in terms of x.
By=-Ax%2BC
y=-Ax%2FB%2BC%2FB
y=-%28A%2FB%29x%2BC%2FB

This shows you that the slope of Ax%2BBy=C would be -A%2FB. A line perpendicular to it would have a slope B%2FA.
