<span>To find the slope of a line use the Point Slope Formula which is: (y2-y1) / (x2-x1)
The point with the bigger x value is (x2,y2)
Next, plug the two points into the formula: (-4 - 5) / (4 -(-2))
Note: 4-(-2) = 4+2 = 6
Simplify: -9 / 6 = - 3/2
The answer is B.
Hope this helps, and May the Force Be With You!

Answer:
22.5
Step-by-step explanation:
You time 75 by 60. Then, you divided it by 200. The answer is 22.5.
Since the distances were the same you can find the average speed directly by adding the speeds then dividing by 2. No need to weight anything.
If we’re considering speed regardless of direction, the average speed is:
(24 + 16) / 2 = 40 / 2 = 20mph
However if direction matters, then one number has to be negative since the directions are opposite:
(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)
Depending on the context, either of these could be your answer.
B. Between 20 and 25 minuets
Brooke's speed is decreasing between 20 and 25 minutes. According to the graph Brooke's speed is decreasing during that time period.
