Interpreting Graphs in 7th Grade Math

What are the two main goals of today's lesson?

• Solving equations and plotting points

• Drawing graphs and calculating ratios

• Interpreting graphs and finding the constant of proportionality

• Understanding graphs and finding the slope

How can you tell if a graph represents a proportional relationship?

• It is a curved line

• It goes through the origin and is a straight line

• It has a negative slope

• It has a positive slope

What does the point (4, 5) represent in the context of a snail's journey?
