The line of best fit for a scatter plot is shown below:

A scatter plot and line of best fit are shown. Data points are located at 0 and 1, 2 and 1, 2 and 3, 4 and 3, 4 and 5, 6 and 3, 7 and 5, 9 and 4. A line of best fit passes through the y-axis at 1 and through the point 4 and 3.

What is the equation of this line of best fit in slope-intercept form? (4 points)


y = 1x + one half


y = one half x + 1


y = 1x − one half


y = negative one half x + 1

4 points

The graph below shows the number of cups of coffee Sherwin consumed in one day and the number of hours he slept that same night:

A scatter plot is shown. Data points are located at 1 and 9, 3 and 5, 5 and 6, 4 and 4, 2 and 7, and 6 and 4. A line of best fit crosses the y-axis at 10 and passes through the point 6 and 4.

How many hours will Sherwin most likely sleep if he consumes 9 cups of coffee? (4 points)


1, because y = -x + 10


2, because y = -x + 10


9, because y = -x + 10


10, because y = -x + 10

Answer 1
