__ infers how well your sample of data represents the total population of data and the ""true"" population mean.

I guess the question isnt completely typed or the attachment is missing but as long as calculating theslope heres how we calculate it.

As we know the formula to calculate the slope is m = y2 - y1 divided by x2 - x1.

Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.
