Answer:

Horizontal line ⇒ y = -4

Vertical line ⇒ x = -3

Step-by-step explanation:

  • The line is horizontal if the y-coordinates of all points lie on it have the same value
  • The equation of the horizontal line that passes through the point (a, b) is y = b
  • The line is vertical if the x-coordinates of all points lie on it have the same value
  • The equation of the vertical line that passes through the point (a, b) is x = a

∵ A horizontal line passes through the point (-3, -4)

→ That means the y-coordinates of all points on the line have

   the same value

∴ The equation of the line is y = -4

∵ A vertical line passes through the point (-3, -4)

→ That means the x-coordinates of all points on the line have

   the same value

∴ The equation of the line is x = -3
