Answer:
Step-by-step explanation:
2y + 4 = 0 <em>subtract 4 from both sides</em>
2y = -4 <em>divide both sides by 2</em>
y = -2
The slope-intercept form of an equation of a line:
y = mx + b
m<em> - slope</em>
b<em> - y-intercept → (0, </em><em>b</em><em>)</em>
In the equation
y = -2
<em>slope: </em><em>m = 0</em>
<em>y-intercept: </em><em>b = -2 → (0, -2)</em>
<em />
<em>y = -2 - it's a horizontal line</em>
The answer is a total of 9 hours
