Finding the Equation of a Horizontal Line Through
To formulate the equation of a horizontal line passing through the point , use the point-slope procedure.
Step 1 — Identify the slope and point: A horizontal line always has a slope of , so . The given point is .
Step 2 — Substitute into the point-slope form :
Step 3 — Simplify: Multiplying the right side by zero eliminates the expression:
The final equation is , affirming that a horizontal line invariably takes the form .
