$\"\"$

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 $\"\"$ 1, y with 4 and x with $\"\"$ 1 in the equation $\"\"$ .

$\"\"$

Subtract 1 from each side.

$\"\"$

Replace m with $\"\"$ 1 and b with 3 in the equation $\"\"$ .
