impatient much?
The subtraction has to be in the same order for both ∆y and ∆x
Since m = ∆y/∆x, B and D are already eliminated.
And A does the subtractions in opposite order.
So, C
Which of these expressions shows a correct way to set up the slope formula for the line that passes through the points (5, 0) and (6, -6)?
A. 0 - (-6)
----------
6 - 5
B. 6 - 5
---------
0 - (-6)
C. -6 - 0
----------
6 - 5
D. 6 - 5
---------
-6 - 0
