Slope from graph Khan Academy. PLEASE HELP ME!! IM HAVING SO MUCH TROUBLE

Answer:
Step-by-step explanation:
you first have to find two points that pass directly through the graph in this case we have (1,4) and (4,-4)
Now we use y2-y1 divided by x2-x1
in this case -4 - 4 (y2-y1) and 4 - 1 (x2-x1)
giving you -8 and 3
so try putting -8/3 as your answer this is what i would put sorry if it is incorrect
