# Functions

Learn and practice identifying and graphing different types of functions with interactive resources from GeoGebra.

## Middle School

### Graphing Linear Functions Using Ordered Pairs

Use ordered pairs derived from tables, algebraic rules, or verbal descriptions to graph linear functions.

### Intercepts of Linear Relations

Identify and interpret the intercepts of a linear relation in number and word problems.

### Point Point Form of a Line

Write the equation of and graph linear relationships given two points on the line.

### Point Slope Form of Line

Write the equation of and graph linear relationships given the slope and one point on the line.

### Properties of Linear Functions, Graphs, and Equations

Interpret and compare properties of linear functions, graphs, and equations.

### Relations and Functions

Define and distinguish between relations and functions, dependent and independent variables, and domain and range; identify whether relations are functions numerically and graphically.

### Slope as Rate of Change

Describe the slope of a line given in the context of a problem situation; compare rates of change in linear relationships represented in different ways.

### Slope Intercept Form of a Line

Write the equation of and graph linear relationships given the slope and y-intercept.

### Slope of a Line

Find the slope of a line given two points on a line, a table of values, the graph of the line, or an equation of the line in number and word problems.
