1. Consider this scatter plot. (a) How would you characterize the relationship? Be specific and make sure to use the axes labels to help you determine the relationship.
(b) Steve uses the function y = 8x + 38 to model the situation. What score does the model predict for 5 h of homework?
(c) What is the y-intercept of the equation? What does it tell you in regards to this situation?
Answe:

A: The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).

B: Assuming that  is the amount of hours spent doing homework:

Plug in  for ,  

That means that since a  value is the test score (because that's what the y-axis is labeled), your predicted test score is a 64.

C: In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

Here hope this helps
