The table represents some points on the graph of a linear function. What is the slope of the line?

8090 [49]

Answer:

-9/2!

Step-by-step explanation:

For this one, It's a bit hard! But, using the process of elimination, you can tell, that since the Y's are going down, this is a negative slope. Since there was only two answers, and only one was negative, it's -9/2!

I really hope this helped... I know it wasn't the best, but I graphed it for you!
