# Write the equation of the horizontal line that passes through the point (-2, -1)

**Solution:**

As stated in the problem the line is horizontal. This means that its slope is zero.

Mathematically it means that it is a line parallel to the x-axis and passing through y = -1 as shown below:

The horizontal line 1 passing through the point (-2, -1) is represented by the equation y = -1.

There is another horizontal line 2 which is passing through the point (1,2) which also has slope zero as it is parallel to the x-axis and represented by the equation y = 2

## Write the equation of the horizontal line that passes through the point (-2, -1)

**Summary:**

The equation of the horizontal line that passes through the point (2, -3) is y = -1
