What is the rate of rainfall if it falls at 2 cm per hour?

Back

The rate of rainfall is 2 cm per hour.

Front

How do you determine the rate of change from a graph?

Back

The rate of change can be determined by finding the slope of the line on the graph.

Front

What is the equation of a line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot.

Front

How do you write the equation of a line given two points?

Back

Use the formula y = mx + b, where m is the slope calculated from the two points.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

How do you convert the slope-intercept form to standard form?

Back

Rearrange the equation to get Ax + By = C.

Front

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

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

How can you identify a linear relationship from a set of data points?

Back

If the data points can be approximated by a straight line, it indicates a linear relationship.
