Answer:
-1/2
Explanation:
Slope formula:

We have to find the slope for the points (4, 8) and (8, 6).
(x1, y1) - coordinates of the first point (4, 8).
(x2, y2) - coordinates of the second point (8, 6).
Now that we know what the variables stand for, we plug the numbers into the formula.
NOTE: -1/2 is -2/4 in the simplest form.
So, the slope of this equation is -1/2.
