Question 166910
well the answer to the 1st two blanks are {{{change-in-y}}} over the {{{change-in-x}}}

I believe that you mis copied  the next part and it should be the "first of these and not the "second of these".  based on that assumption of mine, the blank should read "by finding the {{{y-values}}}. pay careful attention to the {{{order}}} of the difference

likewise on the last part it should read "finding the difference of the {{{x-values}}}. again pay close attention to the {{{order}}} of the difference
