The following scatter plot shows the number of page views for a popular website and how many people signed up to receive emails from the company for upcoming events. 1) Draw a line of best fit on the scatter plot.
2) Find the slope and y-intercept
3) Write an equation for the line of best fit drawn

Linear Regression

Step-by-step explanation:

We can draw any best line of fit, as long as it is reasonable around the points that are given.

We can just take 2 points and use slope formula and Slope-Intercept Form to find the equation for the best line of fit.

Using Linear Regression, we can determine the true best line of fit using graphing utilities.

Finding the best line of fit

Define 2 points

Point (21600, 205)

Point (27000, 290)

Find slope m

Find equation

Slope-Intercept Form tells us that our slope m = and our y-intercept .

Setting this as function f(x), we can see from the graph that it is extremely accurate (Blue line).

Using Linear Regression

Depending on the graphing calc you have, the steps may be different.

Using a graphing calc, we can use statistics and determine the best best line of fit.

When we determine the values, we should see that our equation would be g(x) (Green Line).
