Given a table of values for a linear function, how can you determine the y-intercept?

• Look for the point where x = 0 in the table of values to find the y-intercept.

• Calculate the average of all x-values in the table.

• Check the highest x-value in the table.

• Look for the point where x = 1 in the table of values.

What is the relationship between the slope of a linear function and its steepness on a graph?

• A steeper slope on a graph corresponds to a constant rate of change in the linear function.

• A steeper slope on a graph corresponds to a non-linear relationship in the function.

• A steeper slope on a graph corresponds to a slower rate of change in the linear function.

• A steeper slope on a graph corresponds to a faster rate of change in the linear function.

How can you identify a linear function from a set of data points in a table?

• Check if the data points form a perfect circle

• Look for patterns in the data that are not linear

What does the rate of change in a linear function tell you about the relationship between the variables?

• The rate of change in a linear function tells you the maximum value of the function.

• The rate of change in a linear function tells you the shape of the function.

• The rate of change in a linear function tells you the starting point of the function.

• The rate of change in a linear function tells you how the dependent variable changes for a unit change in the independent variable.
