What is the slope of a line in a graph?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It is calculated as the rise over run.

How do you calculate the average rate of change?

Back

Average rate of change is calculated by taking the difference in the y-values divided by the difference in the x-values over a specific interval.

What does it mean for a graph to show y as a function of x?

Back

A graph shows y as a function of x if each x-value corresponds to exactly one y-value.

How can you use a trend line in a scatter plot?

Back

A trend line can be used to predict values by extending the line through the data points to estimate y-values for given x-values.

What does it mean if a mapping does not represent y as a function of x?

Back

It means that some x-values are associated with more than one y-value, violating the definition of a function.

How do you determine the total cost for a group of tickets?

Back

Total cost = Number of tickets x Cost per ticket - Discounts.

What is the significance of the y-intercept in a linear graph?

Back

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