I can graph a proportional relationship from a story.
Lesson 2: Graphs of Proportional Relationships
I can graph a proportional relationship from an equation.
I can tell when two graphs are of the same proportional relationship even if the scales are different.
Lesson 3: Representing Proportional Relationships
I can scale and label a coordinate axes in order to graph a proportional relationship.
Lesson 4: Comparing Proportional Relationships
I can compare proportional relationships represented in different ways.
Lesson 5: Introduction to Linear Relationships
I can find the rate of change of a linear relationship by figuring out the slope of the line representing the relationship.
Lesson 6: More Linear Relationships
I can interpret the vertical intercept of a graph of a real-world situation.
I can match graphs to the real-world situations they represent by identifying the slope and the vertical intercept.
Lesson 7: Representations of Linear Relationships
I can write an equation for the relationship between the total volume in a graduated cylinder and the number of objects added to the graduated cylinder.
I can use patterns to write a linear equation to represent a situation.
Lesson 8: Translating to $y=mx+b$
