Converting a Point-Slope to Slope-Intercept Form: (-3, 6) and (0, 0)
In algebra, we learn about different forms of linear equations, including point-slope form and slope-intercept form. In this article, we will explore how to convert a point-slope form to slope-intercept form using the points (-3, 6) and (0, 0).
Point-Slope Form
The point-slope form of a linear equation is given by:
$y - y_1 = m(x - x_1)$
where $(x_1, y_1)$ is a point on the line, and $m$ is the slope of the line.
Slope-Intercept Form
The slope-intercept form of a linear equation is given by:
$y = mx + b$
where $m$ is the slope of the line, and $b$ is the y-intercept.
Converting Point-Slope to Slope-Intercept Form
To convert a point-slope form to slope-intercept form, we need to use the point-slope form equation and manipulate it to get the slope-intercept form equation.
Let's use the point (-3, 6) to convert the point-slope form to slope-intercept form.
Using the Point (-3, 6)
Given the point (-3, 6), we can write the point-slope form equation as:
$y - 6 = m(x + 3)$
To convert this to slope-intercept form, we can start by distributing the $m$ to the terms inside the parentheses:
$y - 6 = mx + 3m$
Now, we can add 6 to both sides of the equation to get:
$y = mx + 3m + 6$
This is the slope-intercept form of the equation, where $m$ is the slope, and $3m + 6$ is the y-intercept.
Using the Point (0, 0)
Given the point (0, 0), we can write the point-slope form equation as:
$y - 0 = m(x - 0)$
Simplifying the equation, we get:
$y = mx$
This is the slope-intercept form of the equation, where $m$ is the slope, and the y-intercept is 0.
Conclusion
In this article, we have seen how to convert a point-slope form to slope-intercept form using the points (-3, 6) and (0, 0). By manipulating the point-slope form equation, we can get the slope-intercept form equation, which is a more useful form for graphing and analyzing linear equations.
