\

The given points are $\"\"$ .

\

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

\

$\"\"$

\

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

\

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

\

Rewrite the mixed mubers as improper fractions: $\"\"$ are $\"\"$

\

$\"\"$

\

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

\

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

\

Rewrite the expression with common denominator.

\

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

\

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

\

$\"\"$ (Reciprocal of $\"\"$ )

\

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

\

$\"\"$ (Multiply: $\"\"$ )

\

$\"\"$ (Divide: $\"\"$ )

\

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

\

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