How do you find the slope that is perpendicular to the line #-15 +3y = -12x#?
See a solution process below:
First, we need to find the slope of the line in the problem. We can transform this equation into 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 of the line in the problem is:
Let's call the slope of a perpendicular line:
The slope of a perpendicular line is the negative inverse of the slope of the line it is perpendicular to.:
