Question

A scatter plot of data showing the percentage of total internet users who visited an online store on a given day in December includes the points (2008,2.0) and (2010,4.5). Write the slope intercept form of an equation for the line of fit.

Answer 1

So first you need to find the slope.
\[m=\frac{ \Delta y }{ \Delta x }=1.25\]
Then you use the slope-intercept form equation, one of your points, and the slope to figure out the y-intercept.
\[y=mx+b \rightarrow 2.0=1.25(2008)+b=-2508\]
And last step is to right your slope form equation:
\[y=1.25x-2508\]

Answer 2

Is that the answer

Answer 3

It should be.
