Answer:9)B
10)C
Step-by-step explanation:
The guide can help you to learn how to do this yourself.
<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!
