# How do you graph y=-1/3x?

Nov 28, 2016

$y$ is a straight line through the origin with a slope of $- \frac{1}{3}$

#### Explanation:

The equation of a straight line in slope $\left(m\right)$ and intercept $\left(c\right)$ form is:
$y = m x + c$

In this example: $y = - \frac{1}{3} x$
$\therefore m = - \frac{1}{3}$ and $c = 0$

Hence: $y$ is a straight line through the origin with a slope of $- \frac{1}{3}$

The graph of $y$ is shown below.
