Answer:
-1
Explanation:
"Gradient" is yet another term for "slope" or "rate of change." It is the ratio of "rise" to "run."
Here, the graph goes through grid intersections such that 1 to the right is 1 down. The "rise" is -1 for a "run" of 1, and the slop (gradient) is ...
m = rise/run = -1/1 = -1
The gradient of the graphed line is -1.
