Question 58241
Parallel to y-1=0 with y-intercept (0,-1)
y-1=0
y-1+1=0+1
y=1
This is a special case.  Any time you have y=k, where k is a real number and there's no x, you have a horizontal line going through k.  In this case y=1 is a horizontal line going through y=1.  Horizontal lines have slopes of 0 because y never changes.
A line parallel to a horizontal line would also be parallel.  Horizontal lines have the same y value for every point.
The equation of a horizontal line going through (0,-1) is {{{highlight(y=-1)}}}
Happy Calculating!!!
