#-5/4#

Explanation:

Use the slope fomula:

#m=(y_2-y_1)/(x_2-x_1)#

You do the second #y_2# (which is #-1#) minus the first #y_1# (which is #4#), over the second #x_2# (which is #2#) minus the first #x# (which is #-2#).

#(-1 - 4)/(2 - (-2))#

Then you solve the top and bottom and are left with

#-5/4#

Which is your slope
