Question

a student finds the slope of a line between (14,1) and (18,17). she writes 1-17/18-14 what mistake did she make?

Answer 1

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

I hope this helps!

Answer 2

slope is y2-y1/x2-x1
if this was set up correctly it would be 17 - 1/18 - 14
The student simply switched the places of the y change calculation.
