To find the equation of a line given the slope and an ordered pair, we can use the point-slope form of the equation of a line, which is \( y - y_1 = m(x - x_1) \). Here, \( m \) is the slope, and \( (x_1, y_1) \) is the given point. Since the slope is 0, the line is horizontal, and the equation simplifies to \( y = y_1 \).
Solution Approach
Identify the slope \( m \) and the ordered pair \( (x_1, y_1) \).
Use the point-slope form of the equation of a line.
Simplify the equation to the form \( y = y_1 \).
Step 1: Identify the Given Values
We are given the slope \( m = 0 \) and the ordered pair \((-5, -6)\).
Step 2: Use the Point-Slope Form
The point-slope form of the equation of a line is:
\[ y - y_1 = m(x - x_1) \]
Substituting the given values:
\[ y - (-6) = 0(x - (-5)) \]
Step 3: Simplify the Equation
Since the slope \( m = 0 \), the equation simplifies to:
\[ y + 6 = 0 \]
\[ y = -6 \]
