The points are $\"\"$ and $\"\"$ .

The slope of the line passing through the points $\"\"$ is $\"\"$ .

$\"\"$ (Slope formula)

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Product of two same signs is positive) \ \

$\"\"$

$\"\"$ (Subtract: $\"\"$ )

$\"\"$ (Divide numerator and denominator by $\"\"$ )

So, the slope is $\"\"$ .
