MA19.7A.5
Graph proportional relationships.

Unpacked Content

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.
