Scatter plots

y intercepts, slopes, and patterns

By Teresa Duppstadt

Find the slope of the trend line the same way as you do for a line

Diff in y's/Diff in X's

Rise/Run

3.5 - 1.5/13-6 = 2/7

Slope of Trend Line

The y intercept is where the Trend Line crosses the y axis.

Same as you did when finding the y intercept of a line.

Y intercept = 27

Y intercept of Trend Line

Correlations

Some text here about the topic of discussion

Negative Correlations - y decreases while x increases

Positive Correlations - x and y increase

No Correlations - x and y are not related

Multiple Choice

What is a scatter plot?

A graph that shows the relationship of two data sets.

A graph drawn using rectangular bars to show how large each value is.

A graph that shows information that is connected in some way.

A graph that shows data changing over time.

Multiple Choice

What is a line of best fit (Trend Line) used for?

To make predictions

To make the graph look pretty

To connect the points

Multiple Choice

Which of the following are ways to find the rate of change?

change in y over change in x

rise over run

subtract y coordinates over subtract x coordinates

all these methods will work

Multiple Choice
