Question

Write a mathematical scenario to describe each of the scatter plots

Examples:

Graph #1) Here we are seeing a graph showing a positive-linear relationship between the variables. This could show the relationship between hours of study a student spends during a week (the x variable on the horizontal axis) and the exam grade (the y variable on the vertical axis, out of say 25 points) that student gets. We see here that the more hours a student spends studying the higher their exam grade is.

Graph #2) Here we are seeing a graph showing a negative-linear relationship between the variables. This could show the number of absences a student has over the course of a semester (the x variable on the horizontal axis) and their grade on a final exam (the y variable on the horizontal axis, out of 25 points). It would seem that as the number of absences increase the exam grade will fall.
