Answer:
-3/4
Explanation:
We can see that we have 2 points already marked, (-2,-1) and (2, -4).
To find the slope, it's:
with rise being the units up/down, and run being the units left/right.
Start at point (-2, -1), and count the units going down (in red), and the units going to the right (in yellow), until we come across point (2,-4). We can see that we go down 3 units, and to the right 4 units, giving us a fraction of -3/4.
So, the slope is
.
Hope this helps! :)
edit: let me know if you want the point-slope formula + explanation on this too
