8.4C-Practice

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the starting value of the dependent variable when the independent variable is zero.

Front

How do you find the unit rate from a graph?

Back

The unit rate is found by determining the amount of change in the dependent variable for each unit of change in the independent variable.

Front

What is the definition of revolutions per minute (RPM)?

Back

Revolutions per minute (RPM) is a unit of rotational speed that indicates the number of complete revolutions made by an object in one minute.

Front

How do you calculate earnings per hour?

Back

Earnings per hour can be calculated by dividing the total earnings by the total number of hours worked.

Front

What does the rate of change represent in a graph?

Back

The rate of change indicates how much the dependent variable changes for a unit change in the independent variable, often expressed as a slope.

Front

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, indicating a constant rate of change.

Front

What is the formula for calculating slope?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What does it mean if a graph is increasing?

Back

An increasing graph indicates that as the independent variable increases, the dependent variable also increases.

Front

What is the significance of the x-axis in a graph?

Back

The x-axis represents the independent variable in a graph, which is the variable that is manipulated or changed.

Front

What is the significance of the y-axis in a graph?

Back

The y-axis represents the dependent variable in a graph, which is the variable that is measured or observed.
