\

The line equation in slope-intercept form is $\"\"$ , where m is the slope and b

\

is the y-intercept.

\

First find the slope (m).

\

Slope formulae is $\"\"$

\

Substitute the coordinates of points into the slope formula.

\

$\"\"$ (Replace $\"\"$ with 6, 1, 8 and -4)

\

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

\

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

\

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

\

Slope is $\"\"$

\

$\"\"$

\

Next find the y-intercept (b).

\

$\"\"$ (Substitute -5 for m)

\

$\"\"$ (Substitute 6, 1 for x, y)

\

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

\

$\"\"$ (Add 30 to each side)

\

$\"\"$ (Apply Commutative property: $\"\"$ )

\

$\"\"$ (Apply Additive inverse property: $\"\"$ )

\

$\"\"$ (Apply Additive identity property: $\"\"$ )

\

$\"\"$ (Add: $\"\"$ ) $\"\"$

\

Substitute $\"\"$ for m and 31 for b in the Slope-intercept form equation.

\

$\"\"$

\

$\"\"$

\

The line equation in slope-intercept form is $\"\"$ .
