I need help please

if the equation has a slope of 0, then it's a horizontal line, and in this case, that line is 1 because 1 = 0+B and b=1
the answer is y=1
Answer:
First option, y=1
Step-by-step explanation:
linear eq: y=mx+b, slope m=0, then equation is like y=b (here we have y value as 1)
thus, y=1
