FLASHCARD QUESTION

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how much y changes for a one-unit increase in x.

What is the y-intercept in a linear function?

Back

The y-intercept is the value of y when x is 0. It is the point where the line crosses the y-axis.

FLASHCARD QUESTION

Front

How do you determine the correlation from a scatter plot?

Back

To determine the correlation from a scatter plot, observe the direction of the points: if they trend upwards, it's positive; if they trend downwards, it's negative; if they are scattered without a clear trend, there is no correlation.
