# How do you graph the equation by plotting the points y = x - 2?

Oct 23, 2017

Plot the y-intercept and then use the rise over run method.

#### Explanation:

To graph any equation, you just pick points and connect them. If you are asking how to graph a linear equation such as $y = x - 2$ without having to pick random points, then keep reading.

$y = m x + b$ (slope-intercept form)
$y = x - 2$
The linear equation in question is in a slope-intercept form. The slope$= m = 1$ and the y-intercept$= b = - 2$.

First, we plot our y-intercept which is equal to -2. This means that our y-intercept is at $\left(0 , - 2\right)$. Graph the point $\left(0 , - 2\right)$.

Second, we know that our slope is equal to 1. This means that from our y-intercept that we graphed, we will plot points by doing the rise over run method. Since our slope $m$ is equal to 1, then $m = 1 = \frac{r i s e}{r u n} = \frac{1}{1}$. This means that we will go 1 unit up and 1 unit to the right.
