Answer:
<h2><em>B) y- 4 = 0</em></h2>
Step-by-step explanation:
The general form of an equation of a line:
<em>Ax + By + C = 0</em>
<em></em>
We have the line with a slope = 0. Therefore it's a horizontal line.
The equation of a horizontal line:
<em>y = a</em>
The line passes through points with coordinates in form (x, a).
We have the point <em>(0, 4)</em>. Therefore the equation of this line is <em>y = 4</em>.
Convert to the general form:
<em>y = 4 </em><em>subtract 4 from both sides</em>
<em>y - 4 = 0</em>
