I believe it is B. I did not look at the both the given points but one of the points that are unidentified and one of the given points:
(0, -8) and (2, -2)
To find slope use this equation:
(Y2 - Y1)/(X2 + X1)
Input the points into the equation:
(-2 - (-8))/(2 - 0) —> (-2 + 8)/(2 - 0)
You find that it becomes:
6/2
Then simplify it:
3/1
So the answer is A
