Maddie’s math teacher plots student grades on weekly quizzes against the number of hours they work on classwork a week and then draws the line of best fit Write an equation in slope intercept form of the trend
The equation in slope-intercept form of the trend line is:
y = mx + b
where y represents the student grades, x represents the number of hours worked on classwork per week, m represents the slope of the line, and b represents the y-intercept.
The slope of the trend line, m, represents how the student grades change with each additional hour spent on classwork. The y-intercept, b, represents the expected student grade when the number of hours worked on classwork is zero.
Write an equation in slope-intercept form of the trend line.
