What is a linear relationship?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph. The rate of change is constant.

Front

What is a non-linear relationship?

Back

A non-linear relationship is a relationship between two variables that does not form a straight line when graphed. The rate of change varies.

How can you identify a linear function from a table of values?

Back

If the differences between consecutive y-values are constant for equal intervals of x, the function is linear.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

What is the formula for calculating the slope (m) between two points (x1, y1) and (x2, y2)?

Back

m = (y2 - y1) / (x2 - x1)
