Knowledge
Students know:
- what a proportion is and how it isrepresented on a table or verbally.
- how to graph coordinates and identify the origin and quadrantson the coordinate plane.
Skills
Students are able to:
- create graphs to visually verify a constant rate as a straight line through the corresponding coordinates and the origin.
- Identify the unit rate (constant of proportionality) within two quantities in a proportional relationship shown on a graph and in the form y =mx
Understanding
Students understand that:
- unit rate is sometimes referred to as the constant of proportionality.
- proportional relationships are represented by a straight line that runs through the origin.
- The y=mx is the equation form that represents all proportions, where m is the rate of change/constant of proportionality which can now be called the slope.
