#(5-y)=-2(-2-x)#

Explanation:

The formula for Point-Slope Form is (#y#-#y_1#)=#m#(#x#-#x_1#).

Since you already have your points, all you need to do is find your slope which is #"change in y"/"change in x"# or #(y_2-y_1)/(x_2-x_1)#.
So let's plug in the values:
#(-1-5)/(1-(-2))#

#=(-6)/(3)#
The slope is #-2#.

Now by substituting you first set of points and your slope into the formula, you get #(5-y)=-2(-2-x)#.
