Question

How do you write the equation of the horizontal line passing through the point (4, 7)?

Answer 1

The equation of the horizontal line passing through `(4,7)` is `y=7`.

Explanation:

Equation of a horizontal line line is always of the type

`y=k`

As in the pint `(4,7)` ordinate is `7`

the equation of the horizontal line passing through `(4,7)` is `y=7`.

Note `-` The equation of a vertical line is always of the type `x=k` and hence the equation of the vertical line passing through `(4,7)` is `x=4`.
