Question

What is the equation of the horizontal line that passes through the point (2, -3)?

Answer 1

see below:

Explanation:

If the line is horizontal then it is parallel to x-axis which means its slope is 0.

so you can use 'point slope formula' to get the equation.I'm using that to solve it.

point slope formula---`(y-y1)/(x-x1)=m` (where m=slope)

so according to this ,eqn will be:
`(y+3)/(x-2)=0`

simplifying it :

`y+3=0`
therefore, `y=-3` (the final answer.)
