Quick Links :

Converting an equation from standard form to slope-intercept form can seem daunting, but with the right steps, it can be a breeze. In this article, we will explore the process of converting the equation X 2y 10 to slope-intercept form.

Understanding the Equation

Before we dive into the conversion process, let's take a closer look at the equation X 2y 10. This equation is in standard form, which is typically written as Ax + By = C, where A, B, and C are constants.

What is Slope-Intercept Form?

Slope-intercept form is a way of writing a linear equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept. The slope-intercept form is useful because it allows us to easily identify the slope and y-intercept of a line, which can be helpful in graphing and analyzing linear equations.

Converting to Slope-Intercept Form

To convert the equation X 2y 10 to slope-intercept form, we need to isolate the variable y. We can do this by adding 2y to both sides of the equation, which will get rid of the negative term.

X + 2y = 10

Next, we want to get y by itself on one side of the equation. We can do this by subtracting X from both sides of the equation.

2y = -X + 10

Now, we want to solve for y. We can do this by dividing both sides of the equation by 2.

y = (-X + 10) / 2

y = -1/2X + 5

And there we have it! The equation X 2y 10 in slope-intercept form is y = -1/2X + 5.

Breaking Down the Slope-Intercept Form

Now that we have the equation in slope-intercept form, let's take a closer look at what it means.

• The slope of the line is -1/2, which means that for every one unit increase in X, the value of y decreases by 1/2 unit.
• The y-intercept of the line is 5, which means that the line crosses the y-axis at the point (0, 5).

Tips and Tricks

Here are a few tips and tricks to keep in mind when converting equations to slope-intercept form:

• Always isolate the variable y by adding or subtracting the same value to both sides of the equation.
• Use inverse operations to solve for y. For example, if you have 2y = 10, you can divide both sides of the equation by 2 to solve for y.
• Check your work by plugging the slope-intercept form back into the original equation to make sure it is true.

Common Mistakes

Here are a few common mistakes to watch out for when converting equations to slope-intercept form:

• Forgetting to isolate the variable y.
• Using the wrong inverse operations to solve for y.
• Not checking your work to make sure the slope-intercept form is true.
