Question

Find the equation of the line whose slope is 0 and that contains the point (-4, 2).
Answer
y + 4 = 0
x + 4 = 0
x - 2 = 0
y - 2 = 0

Answer 1

slope is 0
so it is a horizontal line passing by (-4, 2)
its equation is
y=2-----> y - 2 = 0

Answer 2

thank you

Answer 3

my pleasure :D

Answer 4

Always go back to y eeeequaaals mx + b

y=mx+b

(x,y): your point

m: your slope

b: y-intercept

To approach this, you have (x,y), you have m, but you don't have b. You plug in the values you know and solve for b.

2 = (0)(-4) +b

b=2

So we have our b-value, along with our m-value. We don't need the (x,y) to make our eqn of a line.
Plug all of these in and we get our line.

y = (0)*x +2

y = 2

Or like they put it, you can rearrange and get: y -2 = 0

Answer 5

yup this works at any time ;)
