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

b is the y-intercept.

First find the y-intercept value.

$\"\"$ (Substitute 4 for m)

$\"\"$ (Substitute 0, 0 for x, y)

$\"\"$ (Apply zero product property: $\"\"$ )

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

Substitute 4 for m and 0 for bin the Slope-intercept form equation.

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