Need some help boyss

Answer: 0
Step-by-step explanation: The answer would be 0 since if y = -4, the graph of the line would just be a horizontal line through the point (0,-4). This would be like saying that y = 0x-4. Hope this helped!
Answer:
slope = 0
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
y = - 4 ← is therefore a horizontal line
with slope = 0
