Is it Linear?

Front

What is a linear graph?

Back

A linear graph is a graph that represents a linear relationship between two variables, showing a straight line when plotted.

Front

What is a non-linear graph?

Back

A non-linear graph is a graph that does not form a straight line, indicating a non-linear relationship between the variables.

Front

How can you identify a linear graph?

Back

A linear graph can be identified by its straight line, constant slope, and equal intervals between points.

Front

What does it mean if a table of values is linear?

Back

If a table of values is linear, it means that the change in the dependent variable is consistent for equal changes in the independent variable.

Front

What is the slope of a linear graph?

Back

The slope of a linear graph is the ratio of the rise (change in y) to the run (change in x), indicating the steepness of the line.

Front

What is the y-intercept in a linear equation?

Back

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

Front

What is the equation of a linear graph?

Back

The equation of a linear graph is typically written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for a relationship to be non-linear?

Back

A non-linear relationship means that the change in one variable does not produce a constant change in another variable, resulting in a curve.

Front

Can a linear graph have a negative slope?

Back

Yes, a linear graph can have a negative slope, indicating that as one variable increases, the other decreases.

Front

What is an example of a linear relationship in real life?

Back

An example of a linear relationship is the relationship between distance and time at a constant speed.
