# Math Example--Linear Function Concepts--Graphs of Linear Functions in Slope-Intercept Form: Example 11

## Topic

Linear Functions

## Description

This example demonstrates the process of graphing a linear function with a slope of 0 and a y-intercept of 5. The procedure involves three key steps: plotting the y-intercept at (0, 5), recognizing that a slope of 0 results in a horizontal line, and drawing the line parallel to the x-axis through the y-intercept.

Linear functions are essential in algebra, providing a straightforward way to visualize relationships between variables. This collection of examples aids in teaching the topic by presenting various scenarios with different slopes and y-intercepts, allowing students to observe how these parameters affect the position and orientation of the line on the coordinate plane, particularly when dealing with zero slopes resulting in horizontal lines.

Providing multiple worked-out examples is crucial for students to fully grasp the concept of graphing linear functions. By encountering a variety of cases, students can recognize patterns, understand the relationship between the equation and its graph, and develop the skills to approach similar problems with confidence, especially when working with special cases like horizontal lines.

Teacher Script: "Let's look at our eleventh example. We have a linear function with a slope of 0 and a y-intercept of 5. First, we'll plot our y-intercept at (0, 5). Now, here's something interesting: a slope of 0 means that for any change in x, there's no change in y. What does this tell us about our line? That's right, it's horizontal! So, we'll draw a straight line parallel to the x-axis passing through our y-intercept. Notice how this line is different from all our previous examples. What does a horizontal line tell us about the relationship between x and y in this function?"
