Question 84055
#1 correct


#2
The equation of {{{y=4}}} really looks like {{{y=0x+4}}} where the slope is 0

*[invoke equation_parallel_or_perpendicular "parallel", 0, 4, 3, -5]

So the line that is parallel to {{{y=4}}} and goes through (3,-5) is {{{y=-5}}}

It's hard to see, but there are 2 horizontal lines at y=4 and y=-5
