The first thing you have to do is:
subtract: 11-5
Then subtract: -4-(-2)
then you put it as a fraction: 6/-2 or -3
That -3 would be considered the slope.
So now you have: y=-3x+ b
So what you have to do is plug in one of the points into the equation to find out what b is.
For example: 11 = -3(-4) + b
11=12 + b
-12 -12
b = -1
So the answer is: y = -3x -1
