Step 2 enter the data
Step 2: Enter the data

Column A: input valuesColumn B: output values

For this example, I used the data from the Building and Combining functions task. Column A represents number of years since 2000; column B represents the crime rate for City A.


Step 3 graph the data
Step 3: Graph the Data

1. Go to:

Tools,

Graph,

Scatterplot

2. Designate the input values (horizontal) and output values (vertical)

For this example, Column A, number of years since 2000, is my input/horizontal and Column B, crime rate for City A, is my output/vertical


Step 4 draw regression models
Step 4: Draw Regression Models

1. Go to:

Options,

2. There you

have it, the

equation for the

line of best fit!
