Parallel & Perpendicular Slopes

For lines to be PARALLEL they will never cross and have the

• same slopes

• same y-intercept

• same format

• opposite reciprocal slopes

What is the equation of the line shown?

• -4x+2y=8

For lines to be PERPENDICULAR they will cross at a 90 degree angle and their slope are

• opposites

• reciporocals

• opposite reciprocals

• exactly the same

A slope that would be PERPENDICULAR to 4 is ...

• 4

• 1/4

• -4

• -1/4
