First find the slope of the line.

\

$\"\"$

\

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

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

\

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

\

Next find the y-intercept value by replacing m with 1, y with 2 and x with 4 in

\

the equation $\"\"$ .

\

$\"\"$

\

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

\

$\"\"$ (Subtract 4 from each side)

\

$\"\"$ (Apply commutative property of addition: $\"\"$ )

\

$\"\"$ (Apply additive inverse proeprty: $\"\"$ )

\

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

\

Replace m with 1 and b with –2 in the slope-intercept form line equation

\

$\"\"$ .

\

$\"\"$ (Simplify) $\"\"$

\

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