Astudent finds the slope of the line between (8, 17) and (1, 4).
17-4
she writes -. what mistake did she make?
1-8
o
a she used y-values where she should have used x-values.
o
b
she should have added the values, not subtracted them.
c she mixed up the x- and y-values.
c
d
she did not keep the order of the points the same in the numerator
and the denominator.

D.She did not keep the order of the points the same in the numerator

and the denominator

Step-by-step explanation:

Slope of a line is given as  

Here we can see that the order of the points to be taken are in the same in numerator and the denominator

our student found the slope of the line between (8, 17) and (1, 4).  and She wrote

Hence we can see that the order is not the same . It should be

Hence our answer is D.
