answer:
-2/3
Explanation:
we have two points that perfectly meet the graph. those are (2,0) and (5,-2)
slope is formatted as rise/run, with rise being how many up/down and run being how many left/right to the next perfect point.
you have 3 right (5-2) and -2 down (-2-0).
your slope would be -2/3.
we can verify this by counting 2 down and 3 right, and the graph is negative which helps. (aimed downward on the right side)
we do not need to find b (where the line intersects the y-axis) because it only asked for m)
