Question

Choose the equation of the horizontal line that passes through the point (-5, 1)

Answer 1

y = 1

Explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through.

the line passes through (- 5, 1) with y- coordinate of 1, hence

y = 1 ← equation of horizontal line

Answer 2

`y=1`

Explanation:

We are asked to find the equation of the horizontal line that passes through the point
`(-5,1)`.

We know that equation of a horizontal line is in form
`y=a`, which crosses y-axis at point
`(0,a)`.

Since y-coordinate of our given point is 1, so value of a is 1.

Therefore, our required equation would be
`y=1`.
