What's Positive Correlation?
If the y-value increases as the x-value increases then you have a positive correlation. Meaning that the line-of-fit has a positive slope.

What's Negative Correlation?
If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

How Do You Use a Scatter Plot to Find a Line of Fit?
What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.

What is the Range of a Relation?
The teacher illustrates several ways to look at what the range is in a set of numbers. Input, output, stem and plot table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of range.

What are the Coordinate Axes?
The coordinate axes are the x-axis, which is the horizontal axis, and the y-axis, which is the vertical axis. Remember, these axes go on forever.
