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

m=(y1-y2)/(x1-x2)

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.

(1+7)/(9-10)

= 8/-1

= -8

To find the slope of a line, you can use the formula:

m = (y2 - y1) / (x2 - x1),

where (x1, y1) and (x2, y2) are the coordinates of the two points on the line.

In this case, the pair of points given are (9,1) and (10,-7).

Plug in the values into the formula:

m = (-7 - 1) / (10 - 9) = (-8) / 1 = -8.

Therefore, the slope of the line is -8.

So, the answer is m = -8.
