There are an infinite number of such subsets. One of them is the set of real numbers in the interval (7, 8). Perhaps you're thinking "irrational" numbers, as opposed to "integers" or "rational" numbers.

A scatter plot containing the point (5,9) has the regression equation y = -x-3 (see photo)

Tatiana [17]

The residual is the difference between the plotted point and the line of best fit.

We first need to know the point at x=5 for the line of best fit.
y1 = -(5) - 3 = -8

Now we need to find the difference between the line of best fit and the plotted point.
residual = 9 -(-8) = 9 + 8 = 17 or C
