Slope of the line for (1,2) and (2,-3)

-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
