Section 1.3 and 1.4 Vocabulary
Instructions:

an equation in the form y = mx + b, where m is the slope and b is the yintercept of the line

an equation in the form yy₁=m(xx₁) where ( x₁,y₁ ) are coordinates of a point on the line and m is the slope of the line.

two nonvertial lines, if and only if they have the same slope. All vertical lines are parallel.

two nonvertical lines, if and only if the product of the slopes is  1 (the slopes are negative reciprocals of one another). All vertical and horizontal lines are perpendicular.

How much a quanity changes on average, relative to change in another quanity, over time.

Rise over Run
