Question

What is the equation of the horizontal line through (-4,6)

Answer 1

`y = 6`

EXPLANATION

The equation of a horizontal line passing through:

`(x_1,y_1)`

is given by

`y=y_1`

The equation of the horizontal line through (-4,6) is

`y = 6`

Answer 2

y = 6

Explanation:

We are to find the equation of the horizontal line which passes through the point (-4,6).

Since the line is horizontal so the slope will be zero and the equation will be
`y = c` for some constant
`c`.

We know that the line passes through the point (-4,6) so the constant
`c` will be 6 at all points on the line.

Therefore, the equation of the horizontal line will be y = 6.
