Answer: -4
The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right. 
Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4. 
rise/run
4/run
Left and right, the difference is only one unit. 
4/run
4/1
4
This graph is also negative, so let’s add that in. 
-4
This is your answer! I know it wasn’t one of the options you provided, but I’m pretty sure that this is the answer.

Answer:
-40, - 42 and -44
Step-by-step explanation:
The fastes way here is trying. Lets pick a number, intelligently, and then work on it. 
We need three even integers that sum -126. These will be all negative numbers and as they are consecutive they will be very similar (for example, -33 and -35 and -37). Thus, lets start by 1/3 of -126, which is -42:
(-42)+ (-44) + (-46) = - 132, so -42 no.
Lets go a step back: -40
(-40) + (-42) + (-44) = -126
So, the integers are -40, -42 and -44
