# How do you write the equation of a line with slope -1 and y-intercept 0?

Mar 21, 2017

#### Answer:

$x + y = 0$

#### Explanation:

The equation of straight line is-
$y = m x + c$

Here,

• $m =$ slope$= - 1$

• $c =$y-intercept$= 0$

So, $e {q}^{n}$ of the line will be -

$y = m x + c$

$y = - x + 0$

$x + y = 0$

The graph of the above line is -

graph{x+y=0 [-10, 10, -5, 5]}
