Introduction

In mathematics, linear functions are used to model various real-world scenarios, including the movement of objects. In this article, we will explore a linear function representing the distance of an ant from its home as a function of time. The function is given by $y = 2t + 5$ , where $y$ represents the distance from home and $t$ represents the time in minutes.

The Linear Function

The linear function $y = 2t + 5$ can be broken down into two parts: the slope-intercept form and the constant term. The slope-intercept form is given by $y = mt + b$ , where $m$ is the slope and $b$ is the y-intercept. In this function, the slope is 2, which means that the ant's distance from home increases by 2 units for every 1 unit increase in time.

The Constant Term

The constant term in the function is 5, which represents the initial distance of the ant from its home. This means that when the ant starts out, it is 5 units away from its home. The constant term is also known as the y-intercept, which is the point where the function intersects the y-axis.

Interpretation of the Constant Term

In the context of the ant's movement, the constant term 5 represents the starting point of the ant's journey. It is the distance from home when the ant begins its movement. This value is crucial in understanding the ant's initial position and its subsequent movement.

Example

To illustrate the concept, let's consider an example. Suppose the ant starts out at a distance of 5 feet from its home. After 1 minute, the ant's distance from home can be calculated using the function $y = 2t + 5$ . Substituting $t = 1$ into the function, we get $y = 2(1) + 5 = 7$ . This means that after 1 minute, the ant is 7 feet away from its home.

Conclusion

In conclusion, the number 5 in the linear function $y = 2t + 5$ represents the initial distance of the ant from its home. It is the starting point of the ant's journey and is crucial in understanding the ant's subsequent movement. The constant term in a linear function provides valuable information about the initial position of an object, and in this case, it helps us understand the ant's starting point.
