Question

Choose the equation of the horizontal line that passes through the point (-8, -7).

y = -8

y = -7

x = -8

x = -7

Answer 1

If it is horizontal, does the y value change (does it go up or down at all?)
I would say no, the y value stays the same (that is what horizontal means)

of course the line has to go through your point (-8,-7)
