Convert 2x + 5 To Slope Intercept Form Easily

Quick Links :

Converting an equation to slope-intercept form is a fundamental concept in algebra, and it's a crucial skill to master for solving linear equations. The slope-intercept form, also known as the y-intercept form, is a way of expressing a linear equation in the form y = mx + b, where m is the slope and b is the y-intercept. In this article, we'll explore how to convert the equation 2x + 5 to slope-intercept form easily.

Understanding the Slope-Intercept Form

Before we dive into converting the equation, let's quickly review the slope-intercept form. The slope-intercept form is a linear equation in the form y = mx + b, where:

• m is the slope, which represents the rate of change of the line
• b is the y-intercept, which is the point where the line intersects the y-axis

The slope-intercept form is useful because it allows us to easily identify the slope and y-intercept of a line, which can be used to graph the line or solve equations.

Converting 2x + 5 to Slope-Intercept Form

Now that we understand the slope-intercept form, let's convert the equation 2x + 5 to slope-intercept form.

To convert the equation, we need to isolate y on one side of the equation. Currently, the equation is in the form 2x + 5, which means that y is not isolated. To isolate y, we can subtract 2x from both sides of the equation.

Step 1: Subtract 2x from Both Sides

Subtracting 2x from both sides of the equation gives us:

y = -2x + 5

Step 2: Identify the Slope and Y-Intercept

Now that we have the equation in slope-intercept form, we can identify the slope and y-intercept.

• The slope (m) is -2, which means that the line slopes downward from left to right.
• The y-intercept (b) is 5, which means that the line intersects the y-axis at (0, 5).

Benefits of Converting to Slope-Intercept Form

Converting an equation to slope-intercept form has several benefits, including:

• Easy graphing: With the slope and y-intercept identified, we can easily graph the line.
