# Sneaking Up on Slope!!!

## Learning Targets

• Graph proportional relationships, interpreting the unit rate as the slope of the graph.
• Compare two different proportional relationships represented in different ways - tables, graphs, equations.
• Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane
• Derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

## Do First
