The slope of a line that goes through both and would be .
Step-by-step explanation:
The slope of a line is the ratio between rise and run between these two points.
The rise between two points is the change to the corresponding coordinates. Between and , the rise would be (subtract the first -coordinate from the second.)
The run between two points is the change to the corresponding coordinates. Between and , the rise would be (likewise, subtract the first -coordinate from the second.)
