Proportional Relationship
Proportional Relationship
A relationship where the ratio between two quantities is constant. This means that as one quantity increases or decreases, the other quantity changes proportionally.
Rate of Change
Rate of Change
The rate of change describes how much a quantity changes with respect to another quantity. In a linear relationship, it's represented by the slope of the graph.
Initial Value
Initial Value
The starting value of a function or relationship. It's the value of the function or output when the input is zero.

Study Notes
Linear Expressions and Equations
- Linear expressions involve variables and constants combined with addition, subtraction, and multiplication.
- Linear equations describe relationships between variables, often represented by a straight line on a graph.
Creating Linear Equations
- Equations can be created from various contexts.
- Equations can be formed using two points or a graph.
- Linear inequalities can be created and solved.
Proportional vs. Non-Proportional Relationships
- Proportional relationships maintain a constant ratio between variables.
- Non-proportional relationships do not exhibit this constant ratio.
- Different representations of proportional relationships exist.
Rate of Change and Initial Value
- Rate of change describes how a variable changes over time.
- Initial value represents the starting point of a relationship.
Arithmetic Sequences
- Arithmetic sequences involve a constant difference between consecutive terms.
- Explicit and recursive formulas define these sequences.
Linear Graphs
- Linear graphs are straight-line representations of relationships between variables.
- Graphs can be interpreted to understand the relationship.
Domain and Range of Linear Graphs
- Domain refers to the set of possible input values (x-values).
- Range refers to the set of possible output values (y-values).
- Interval and set notation describe domains and ranges.
Function Notation
- Function notation represents a relationship between variables.
- Function notation can be applied to tables and graphs.
Linear and Non-linear Functions
- Linear functions result in a straight-line graph.
- Non-linear functions produce non-straight graphs.
- Parent functions represent basic forms of functions.
- Key features describe critical characteristics of functions.
