The line is vertical.
The line is horizontal.
The line has no y-intercept.
The equation of the line is y = negative 2.

Answer 1

Select all that apply:

- The slope is 0. — True (slope = (-2 − (-2)) / (4 − 1) = 0/3 = 0).
- The y-intercept is −2. — True (the line passes through (0, −2)).
- The line is vertical. — False.
- The line is horizontal. — True.
- The line has no y-intercept. — False.
- The equation of the line is y = −2. — True.
