Graphing Horizontal and Vertical Lines

Finding Slope from a Graph

Review: Finding Slope from a Graph  (note:  You must also learn how to find the slope by using the formula)

Finding Slope from a Table

 Visualize the 4 Types of Slope: Positive (+) ⤢, Negative (-) ⤡,  Zero (0) ⟷, Undefined ↕ 

Example: Finding Slope (m) Using the Formula

Finding Slope (m) Using the Formula (note: always reduce slope fractions to lowest form, but leave them improper - no mixed numbers!)

Slope of a Horizontal or Vertical Line (note:  zero divided by any number is zero. Any number divided by zero is undefined)

Slopes of Parallel & Perpendicular Lines

Graphing on the Coordinate Plane

Graph a Proportional Relationship Given a unit Rate (Slope)

Graph a Proportional Relationship from a Table

Graph a Proportional Relationship from an Equation

Direct Variation vs. Partial (Not Direct) Variation

Example: Writing a Direct Variation Equation (remember that k and m are the same thing. So y=mx and y=kx are the same.)

Use Slope to Compare proportional Relationships

Introduction to Standard Form of Equations

Convert from Standard Form to Slope-Intercept Form  (he says "minus" when he should be saying "negative" or "opposite," but otherwise good)
