Astudent finds the slope of the line between (8, 17) and (1, 4). she writes 17-41-8. what mistake did she make? what is the correct answer?

slope = (y2-y1)/(x2-x1)

m =(17-4)/(8-1)

m = 13/7

You have to keep the pairs in the same order

because they could drop even lower..

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
