Answer:
-5/1
Step-by-step explanation:
Remember: Rise over Run
To solve this...
You will need the equation:
y² - y¹
x² - x¹
So now you have to label ( 1 , 2 ) and ( 2 , - 3 ) as either x¹ or y¹ etc.
x¹ = 1 and y¹ = 2
x² = 2 and y² = -3
Now you know your plug ins. Just solve it.
Your equation should look like this now:
-3 - 2 -5
------- = ----- ( so this is your answer )
2 - 1 1
