Find the slope, if it exists, of the line containing the pair of points
(9,1) and (10,-7)
The slope m = __
or the slop is undefined
does not exist if the denominator = 0
Thank you, I could not remember the formula to use.
this is what I got:
M = 1 + 7/ 9 - 10 = 8/-1
I'm still not sure what the slope is.
Thanks in advance for you help.
