# What is the equation of a horizontal line passing through (-3,-5)?

##### 2 Answers

#### Explanation:

If y always equals -5 then the x value will change but the y value will not. This means that the slope of the line is zero and will be parallel to the x axis, which is the horizontal line.

Point-slope form:

Slope-intercept form:

#### Explanation:

A horizontal line has a slope of

**Point-slope form:**

where:

Plug in the known values.

**Slope-intercept form:**

where:

We can convert the point-slope form to slope-intercept form by solving for

graph{y+5=0(x+3) [-9.875, 10.125, -7.52, 2.48]}
