Question

What do the slope and y-intercept mean as they relate to the study time and the number of words spelled correctly?

Answer 1

There is a positive correlation.

Explanation:

As you can see, the LOBF (line of best fit) is positive, as it is getting higher. As are the points. In the graph, at around 4, is the y intercept. As the x's go higher, so do the y's. The slope is making it do that, as the slope is positive.

So in this graph and dataset, the more time that you study, the more words are spelled correctly.

Therefore, there is a positive y intercept, slope, and correlation.

I hope this helps!
