Introduction

In mathematics, the slope-intercept form of a linear equation is a fundamental concept that helps us understand the relationship between the variables in a linear equation. The slope-intercept form is given by the equation y = mx + b, where m is the slope of the line and b is the y-intercept. In this article, we will learn how to convert a given linear equation into slope-intercept form, simplifying all fractions.

Understanding the Slope-Intercept Form

The slope-intercept form of a linear equation is a powerful tool for understanding the behavior of a line. The slope (m) represents the rate of change of the line, while the y-intercept (b) represents the point where the line intersects the y-axis. To convert a linear equation into slope-intercept form, we need to isolate the variable y.

Converting the Given Equation

The given equation is 4x - 20y = -160. To convert this equation into slope-intercept form, we need to isolate the variable y. We can start by adding 20y to both sides of the equation, which gives us:

4x = -160 + 20y

Next, we can divide both sides of the equation by 4, which gives us:

x = (-160 + 20y) / 4

Now, we can simplify the equation by dividing the numerator and denominator by 4, which gives us:

x = -40 + 5y

Simplifying the Equation

To simplify the equation further, we can rewrite it in slope-intercept form by isolating the variable y. We can start by subtracting 5y from both sides of the equation, which gives us:

x - 5y = -40

Next, we can add 5y to both sides of the equation, which gives us:

x = -40 + 5y

Now, we can rewrite the equation in slope-intercept form by isolating the variable y. We can start by subtracting x from both sides of the equation, which gives us:

-5y = -40 - x

Next, we can divide both sides of the equation by -5, which gives us:

y = (40 + x) / 5

Simplifying the Fraction

To simplify the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 5. This gives us:

y = (8 + x/5) / 1

Conclusion

In this article, we learned how to convert a given linear equation into slope-intercept form, simplifying all fractions. We started by adding 20y to both sides of the equation, then divided both sides by 4 to isolate the variable y. We simplified the equation further by dividing the numerator and denominator by 4, then rewrote the equation in slope-intercept form by isolating the variable y. Finally, we simplified the fraction by dividing the numerator and denominator by their greatest common divisor.
