Parallel and Perpendicular Lines Based on Slopes

-Two lines that intersect to form right angles

-Slopes are OPPOSITE RECIPROCAL (flip & switch)

-Lines that Never Intersect

-Slopes are the SAME

The slope for parallel lines will ​ (a)  

and the slope for perpendicular lines will be ​ (b)   .

A figure is shown. If $$\angle SRD=133\degree$$ identify the value of each given angle.

$$\angle CRQ=$$ ​ (a)   $$\angle SRC=$$ ​ (b)  

$$\angle BQP=$$ ​ (c)   $$\angle RQB=$$ ​ (d)  

y = 3x +2
y = 3x - 3
These lines are...

Are these two lines parallel, perpendicular or neither?
y = -1/3x - 5
y = 1/3x + 2

Match the following to its perpendicular slope

y = -2/3x + 2
y = 3/2x + 9
These lines are...

​ (a)   lines intersect to create right angles.
​ (b)   lines never touch and maintain the same distance.

Identify the correct perpendicular slope of each given slope.
