what is the slope of the line shown below?
(-1,8) (2,-4)
A.4
B. -1/4
C.1/4
D.-4
Take the two points ....slope = rise/run = (y1-y2) / (x1-x2)
= (8- -4) / (-1-2) = 12/ -3 = -4
The formula for calculating slope is \(\frac {y2 - y1} {x2-x1}\) . So we have \(\frac{-4-8}{2-(-1)} = \frac {-12}{3} = \frac{-4}{1} = -4\)
