$\"\"$

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

Find the y-intercept value by replacing m with $\"\"$ , y with $\"\"$ 2 and x with $\"\"$ 4 in the equation $\"\"$ .

$\"\"$

Subtract $\"\"$ from each side.

$\"\"$

Replace m with $\"\"$ and b with $\"\"$ in the equation $\"\"$ .
