Slope of line, perpendicular to the line,
Explanation:
Slope of the line,
is
The product of slopes of the perpendicular lines is
to the line,
See a solution process below:
Explanation:
This equation is in Standard Linear Form. The standard form of a linear equation is:
Where, if at all possible,
The slope of an equation in standard form is:
Therefore, the slope for this line is:
Let's call the slope of a perpendicular line:
The slope of a line perpendicular to a line with slope
Substituting the slope for the line in the problem gives:
