A study found that the number of times students texted during the review class and the grade of their Psychology tests has a linear relationship where x represents the number of texts sent and y represents the test score. A student who sent no texts scored a 92, and another student who sent 8 texts scored a 60.
A) Write the information in the problem as two ordered pairs where x represents the number of texts sent and y represents the test grade.
B) Write the equation of the line that passes through these two points.
C) A line that best fits the data is called a regression line. Such a line can be used to make predictions about your y value based on reasonable x values. Using this equation from part (b), what would you predict to be the psychology test score if 15 texts were sent?
