The line of best fit for a scatter plot is shown: A scatter plot is shown. Data points are located at 0 and 8, 2 and 8, 4 and 5, 6 and 3, 6 and 5, 6 and 7, 9 and 4, 10 and 2. A line of best fit passes through the y-axis at 8 and continues downward passing through the point 6 and 5.
What is the equation of this line of best fit in slope-intercept form? (4 points)

a
y = negative one half x + 8

b
y = −2x + 8

c
y = −8x + one half

d
y = −8x + 2
