Question

What is the equation of the line that passes through (0, -2) and has a slope of 0

y=-2
y=2
x=2

Answer 1

do you understand y=mx+b?

Answer 2

because if you do then all you need to do for your problem is plug in numbers and solve

Answer 3

in y=mx+b, your b is your y intercept (another way of saying that is, when x = 0, what is y. in your case, they give that to you). your m is your slope (or rise over run, but they give that to you too.) so for your problem. just plug in what they give you and solve for y.
