Learning ObjectiveG-GPE-5 - Prove the slope criteria for parallel

and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).

Note #14What is the slope of the segment connecting the points (3,7) and (1,7) ?

A horizontal line will always have a slope of 0

H – Horizontal Lines

O – Slope = 0

Y – Their equation is in the form y = a constant
