y2-y1 over x2 - x1 = 9 - 7 / -8 + 5 = -2/3
So the slope is -2/3

To find the slope of a line, you have to find the change in the 2 y-coordinates and put that over the change in the 2 x-coordinates. Like so:
9-7 = 2
---- -----
-8- -5 = -3
It doesn't matter which point you put first, as long as the first coordinates are from the same point.
So the slope is -2/3 or -2 over 3. It also doesn't matter where you put the negative sign.
Hope this helps!

The equation for finding a slope is rise over run or (Y2 - Y1)/(X2 - X1). So your equation should look like this :
(9 - 7) / (-8 - (-5)) = -2/3 This is your slope

slope= m= y2 - y1 / x2 - x1
m= (9-7) / (-8 - -5)
m= 2 / -3
m= -2 / 3
negative slope

slope formula: m=y-y over x-x
(-5,7) (-8,9)
m=7-9 over -5+8
m= -2 over 3
m= (3,-2)
