How do you find the slope that is perpendicular to the line #y=7/5x - 2#?
The slope of a line in slope intercept form (
In this case, the slope is
To find the slope of a perpendicular line, we simply use the negative reciprocal of the number. The reciprocal of
Therefore, the negative reciprocal of
The slope of a perpendicular line is therefore
In other cases, you might need to manipulate the equation to get it in slope intercept form.
