Answer:
4/-9
Explanation:
When finding slope, you use the expression y-y1/x-x1. Now, fill in the coordinates to the expression. It should look like this: 8-4/-3-6. 8-4=4, and -3-6= -9. Now, you have 4/-9. Make sure to simplify your slope after solving. However, this is fully simplified, so your answer is 4/-9.
