What is a solution to a system of equations?

Back

A solution to a system of equations is a set of values that satisfy all equations in the system simultaneously.

Front

What defines a linear function?

Back

A linear function is defined by a constant rate of change and can be represented by a straight line on a graph.

Front

How can you identify a linear function from a table?

Back

A linear function will have a constant difference in the y-values for equal differences in the x-values.

Front

What is a nonlinear function?

Back

A nonlinear function does not have a constant rate of change and cannot be represented by a straight line.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x.

Front

What does it mean for a graph to be linear?

Back

A graph is linear if it forms a straight line, indicating a constant rate of change.

Front

What is the y-intercept of a linear function?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is 0.

Front

How do you determine if a function is linear or nonlinear from a graph?

Back

If the graph is a straight line, the function is linear; if it curves, the function is nonlinear.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.
