4

Step-by-step explanation:

To find the slope, you need to use the following equation:

For x₂ and y₂, I picked 5 and 20.  For x₁ and y₁, I picked 3 and 12.  It doesn't matter which points you pick to plug in.  You will get the same answer regardless.  

Your slope is equal to 4.

If you need me to clear something up, let me know.  Hope this helps! <3
