Examples, solutions, videos and lessons to help Grade 8 students learn how to graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.

Common Core: 8.EE.5

### Suggested Learning Targets

**Graphing Proportions, Rates & Slope (8.EE.5)**

The graph of a proportional relationship is a straight line that goes through the origin.

The constant of proportionality (k) is the constant you get when you divide y and x in a proportional relationship.

The bigger the number represented by k, the steeper the line.
