please help dont know how to do

Answer:
-3
Step-by-step explanation:
We can use any two points in the table and the slope formula
m = (y2-y1)/(x2-x1)
Using ( (0,4) and ( -2,10)
= ( 10 -4)/(-2 -0)
= 6/-2
= -3
Answer:
B. -3
Step-by-step explanation:
If you were to put it into a problem
-2x + 4
(the 4 because that's where it intercepts the y axis)
and if you were to substitute in 4 for the x you would get
-2(4) + 4 = -4 which wouldn't give you -8
so now you try -3x + 4
Then substitute 4 for x
-3(4) + 4 = -8 so then you would substitute 6 by four just to be sure
-3(6) + 4 = -14 so the answer would be B.
