What is the equation of a horizontal line passing through the point (-7, 5)?

Solution:

Given: the point (-7, 5)

Equation of horizontal line passing through (x₁, y₁) is y = y₁

⇒y = 5

The equation is y - 5 = 0

Therefore, the required equation is y - 5 = 0.

Example:

What is the equation of a horizontal line passing through the point (-2, 6)?

Solution:

Given,

The point (-2, 6)

Equation of horizontal line passing through (x₁, y₁) is

y = y₁

y = 6

The equation is y - 6 = 0

Therefore, the required equation is y - 6 = 0.

What is the equation of a horizontal line passing through the point (-7, 5)?

Summary:

The equation of a horizontal line passing through the point (-7, 5) is y - 5 = 0.
