The Equation $y = -750x + 8,500$ Predicts The Price Of A Motorcycle, $y$, After $x$ Years. Using The Equation, Predict The Price Of A Motorcycle That Is 5 Years Old.

Introduction

In the world of mathematics, equations play a vital role in predicting and analyzing various phenomena. One such equation is the linear equation $y = -750x + 8,500$, which predicts the price of a motorcycle, $y$, after $x$ years. This equation is a perfect example of how mathematics can be used to model real-world situations and make predictions about future events. In this article, we will explore the equation, its components, and how it can be used to predict the price of a motorcycle that is 5 years old.

Understanding the Equation

The equation $y = -750x + 8,500$ is a linear equation in the slope-intercept form, where $y$ is the dependent variable (the price of the motorcycle), $x$ is the independent variable (the number of years), and $-750$ is the slope (the rate of change of the price with respect to time). The constant term $8,500$ is the y-intercept, which represents the initial price of the motorcycle.

Breaking Down the Equation

To understand the equation better, let's break it down into its components:

• Slope: The slope of the equation is $-750$, which means that for every year that passes, the price of the motorcycle decreases by $750.
• Y-intercept: The y-intercept of the equation is $8,500$, which represents the initial price of the motorcycle.
• Independent Variable: The independent variable $x$ represents the number of years that have passed since the motorcycle was purchased.

Predicting the Price of a 5-Year-Old Motorcycle

Now that we have a good understanding of the equation, let's use it to predict the price of a motorcycle that is 5 years old. To do this, we need to substitute $x = 5$ into the equation and solve for $y$.

# Define the equation
def motorcycle_price(x):
    return -750 * x + 8500

# Predict the price of a 5-year-old motorcycle
price = motorcycle_price(5)
print(price)

Interpreting the Results

When we run the code, we get a predicted price of $7,250. This means that according to the equation, a 5-year-old motorcycle would be worth $7,250.

Conclusion

In conclusion, the equation $y = -750x + 8,500$ is a powerful tool for predicting the price of a motorcycle based on its age. By understanding the components of the equation and using it to make predictions, we can gain valuable insights into the world of mathematics and its applications.
