Answer:
m = -1/2
Step-by-step explanation:
The slope is the ratio of "rise" to "run". The "rise" is the vertical distance between the two points. The "run" is the corresponding horizontal distance.
Vertical distances are positive in the "up" direction, and horizontal distances are positive in the "right" direction for this purpose. Here, the rightmost point is below the leftmost point, so the "rise" is negative.
slope = m = rise/run = -1/2
The slope is ...
m = -1/2

This must be true for some value of x, since we have a quantity squared yielding a positive number, and since the equation is of second degree,there must exist 2 real roots.
Well he started off correct to the point of completing the square.
