Transforming a Linear Equation into Slope-Intercept Form: Understanding and Application

Linear equations are fundamental in algebra and are widely used in various fields, from economics to physics. One of the most useful forms of a linear equation is the slope-intercept form, y mx b, where m represents the slope of the line and b represents the y-intercept. This form allows us to easily understand and visualize the behavior of a linear relationship.

The Given Equation: -1 2y 14

Let's work through the process of transforming the given equation, -1 2y 14, into slope-intercept form. This equation needs to be manipulated such that it meets the requirements of the slope-intercept format y mx b.

Step-by-Step Transformation

Isolate the y-term: Start the equation by adding 1 to both sides to isolate the term containing y. Divide by the coefficient of y: Once the y-term is isolated, divide every term by 2 to solve for y. The equation becomes:

2y 14 1

2y 15

y 5x 7

From the transformed equation, we can clearly see that the slope m is 5, and the y-intercept b is 7.

General Transformation Process

Isolate the y-term: The y-term should be on one side of the equation with all other terms on the other side. This step is critical for any linear equation to be converted into slope-intercept form. Divide by the coefficient of y: Once the y-term is isolated, divide every term by the coefficient of y to solve for y. The steps for the given equation follow as:

-1 2y 14

2y 1 14

y 5x 7

Again, in this form, the slope m is 5, and the y-intercept b is 7. This process is generic and can be applied to any linear equation to convert it into the desired slope-intercept form.

Conclusion

The ability to transform a linear equation into slope-intercept form is a crucial skill in algebra. Understanding and applying this transformation can help in numerous applications, from graphing lines to analyzing real-world data. Whether you are a student, a teacher, or a professional in a field that uses linear equations, mastering this form is indispensable.
