Front

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the function. It indicates how much the y-value changes for a one-unit increase in the x-value.

What does the term 'rate of change' refer to in linear functions?

Back

The rate of change refers to the slope of the line, indicating how much the dependent variable (y) changes for a unit change in the independent variable (x).

Front

How can you determine if a function is linear from a table of values?

Back

A function is linear if the differences between consecutive y-values divided by the differences between consecutive x-values are constant.

Front

What is the significance of the y-intercept in a real-world context?

Back

The y-intercept often represents the starting value of a situation in real-world problems, such as the initial amount of money in a bank account.

Front

How do you graph a linear function?

Back

To graph a linear function, identify the y-intercept, plot it on the graph, use the slope to find another point, and draw a straight line through the points.
