Observe the graph;

The line is passing through (0, 2) and the line is parallel to x-axis. So, slope is zero. $\"\"$

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

Next find the y-intercept (b).

$\"\"$ (Substitute 0 for m)

$\"\"$ (Substitute 0, 2 for x, y)

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

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

Substitute 0 for m and 2 for b in the Slope-intercept form equation.

$\"\"$

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