Question

the rates of change of two data sets can be compared by finding:
the initial values.
the slope of each trend line.
how close the points are to the line.
the y-intercepts.

Explanation:

To compare the rates of change of two data sets, we analyze the options:

• Initial values (or y - intercepts) represent starting points, not rates of change.
• The slope of a trend line represents the rate of change (rise over run, change in y per change in x).
• How close points are to the line measures the goodness of fit, not the rate of change.

So the slope of each trend line is used to compare rates of change.

Answer:

B. the slope of each trend line.
