What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

What does it mean if a table is not a function?

Back

If a table is not a function, it means that at least one input value is associated with more than one output value.

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b.

How do you solve the equation 5x + 1 = 2x - 5?

Back

To solve 5x + 1 = 2x - 5, first subtract 2x from both sides: 3x + 1 = -5. Then subtract 1 from both sides: 3x = -6. Finally, divide by 3: x = -2.

What is the definition of a dependent variable?

Back

What is the definition of an independent variable?

Back

An independent variable is the variable that is changed or controlled in an experiment, often represented on the x-axis.

Front

What does it mean if a graph is a function?

Back

If a graph is a function, it means that for every input (x-value), there is exactly one output (y-value).
