Answer: Third option.
Step-by-step explanation:
By definition, the slope of a line can be calculated with the following formula:
Since you need to solve for 
to find an equivalent expression, you can apply these steps:
1. You must multiply both sides of the equation by 
:
2. Finally, you must add 
to both sides of the equation:
