What is the equation of a horizontal line passing through the point (2, 10)?
y = 12
x = −8
y = 10
x = 2

Step-by-step explanation:

We know that if a line is horizontal on Cartesian plane then it must be parallel to x axis.

Since , the horizontal line intersect through the y axis at a fix value (a) .

The equation of line :

The given point : (2,10)

The x-coordinate of the point = 2

The y-coordinate of the point = 10

⇒ The horizontal line intersect through the y axis at a fix value of 2.

⇒ The equation of a horizontal line passing through the point (2, 10) =

the 4th choice is the correct one
