Answer: 
Step-by-step explanation:
The slope of a line equals to the difference between points' y-coordinates divided by the difference between their x-coordinates.
That is, if
and
are the point of a line,
Then the slope of the line is,

By the given diagram,
,
,
and 
Thus, the slope of the given line
= 
⇒ Fourth option is correct.
