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

Answer 1

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.

Answer 2

Write an equation in slope-intercept form of the trend line.

y=x+55
y is equal to x plus 55

y=−5x
y is equal to negative 5 x

y=5x+55
y is equal to 5 x plus 55

y=x+60
y is equal to x plus 60
