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