# How do you write an equation of a line with slope -1/2 and y-intercept -5?

Nov 20, 2016

$y = - \frac{1}{2} x - 5$

#### Explanation:

The standardised equation for a straight line is $y = m x + c$

Where $m$ is the gradient and $c$ is the y-intercept.

So directly from the information in the question:

slope (gradient) $\to m = - \frac{1}{2}$
y-intercept $\to c = - 5$

So $y = m x + c \text{ "->" } y = - \frac{1}{2} x - 5$
