Answer:

Step-by-step explanation:
For this situation we have the equation
, where each variable represents a coordinate (e.g. in this case 4 could be
). So first, let's define which coordinates will be the values of these variables:
(3,4): 
(5,9): 
Now we need to replace each variable with its given value: 
And then do the subtraction to simplify: 
Therefore, the slope of the line that passes through the points (3,4) and (5,9) is
.
