Answer:
-1/2
Explanation:
Method 1)
Use the graph
You must go from point (-7, 5) to point (5, -1) by using only vertical and horizontal paths.
Start at point (-7, 5).
Go down 6 units. That means a rise of -6.
Now go right 12 units to point (5, 1)
That is a run of 12 units.
slope = rise/run = -6/12 = -1/2
Method 2)
Use the slope formula
slope = (y2 - y1)/(x2 - x1) = [5 - (1)]/(-7 - 5) = (5 + 1)/(-12) = 6/(-12) = -1/2
