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

Plug it into point-slope form

Answer 2

\(\sf y - y_1 = m(x - x_1)\)

Answer 3

(0, -2)
x1 y1

m = 0

Answer 4

Or point-intercept y=mx+b

Answer 5

since the y intercept is -2 ....

Answer 6

\(\sf y + 2 = 0(x - 0)\)

Answer 7

Simplify

Answer 8

The right side equals 0

Answer 9

y + 2 = 0

Answer 10

Subtract 2 to both sides

Answer 11

-2?

Answer 12

Yes, so we have:

y = -2
