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

• I can determine the rate of change by the definition of slope.
• I can graph proportional relationships
• I can 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 the two moving objects has greater speed)
• I can interpret the unit rate of proportional relationships as the slope of a graph.

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.
