Linear Equations and Their Graphs

Front

Function notation.

Back

Function notation uses symbols like f(x) to represent functions, indicating the output value for a given input x.

Front

Rate of change in a line.

Back

The rate of change is the ratio of the change in the output value to the change in the input value.

Front

Evaluating functions.

Back

To evaluate a function, substitute the input value into the function and solve for the output.

Front

What is point slope form of a linear equation?

Back

Point-slope form: y - y₁ = m(x - x₁)

Front

Slope

Back

The rate of change in a linear equation.

Front

X-intercept

Back

The point where a graph crosses the x-axis.

Front

Domain

Back

The set of all possible input values for a function.

Front

Horizontal Line

Back

A line where all points have the same y-coordinate.

y=#

slope is 0

Front

Intercept

Back

The point where a graph crosses an axis.

Front

Vertical Line

Back

A line where all the x-coordinates are the same.

x=#

slope is undefined
