First let's find the slope of the line passing through the aforementioned points.
y 2 - y 1 x 2 - x 1 Finding the slope using two points
- 5 - 8 20 - 3
- 13 17 This is the slope
Perpendicular slopes are opposite reciprocals of one another.
Opposites: -2 and 2, 4 and -4, -18 and 18, etc.
Add a negative sign to the front of any number to find its negative.
- ( - 13 17 ) = 13 17
To make something a reciprocal of another number, flip the numerator and denominator of the original number.
13 17 17 13
