Answer:
10
Step-by-step explanation:
The formula to find slope with two ordered pairs is: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]. So inserting your numbers, you would do 11- (-9) or 11+9. Your answer for the numerator is 20. Next you do 1- (-1) or 1+1. Your denominator is 2. So your slope is 20/2 or simplified 10.
Hope it helps!
