Question

How do you write an equation of a horizontal line that passes through (8, -5)?

Answer 1

`y=-5`

Explanation:

A horizontal line, parallel to the x-axis is a line that passes through all points in the plane with the same y- coordinate. For this reason it's equation in general is `color(blue)" y = c"` , where c is the value of the y-coordinate that it passes through.

Here the y- coordinate is - 5

`rArry=-5" is the equation of the line"`
