The scatter plot on graph showing the points (1, 7), (2, 6), (3, 5), (4, 3), (5, 4), (6, 2), (6, 3), (7, 3), (8, 1), and (8, 2).
Which linear equation would best fit the data points plotted?
a
\large y=-7.5x+1
b
\large y=7.5x+1
c
\large y=-1x+7.5
d
\large y=1x+7.5
Since the data points do not appear to follow a linear pattern, it is difficult to determine the best-fit linear equation just by looking at the scatter plot. However, we can use a mathematical tool called linear regression to find the equation that best fits the data. Using linear regression, we find that the best-fit equation is:
\large y = -0.669x + 6.384
None of the answer choices match this equation. Therefore, none of the given options are correct.
