# How do you graph the equation y=-x-3?

May 6, 2018

You should plug in any number for x which can be positive or negative numbers.

#### Explanation:

graph{y=-x-3 [-10, 10, -5, 5]}

So you can plug in any numbers for x. So let plug 0 in for x.

y = - (0) - 3
y = -0 - 3
y = -3

Now, you should also remember to distribute the negative sign, otherwise, you will receive incorrect values. Let plug another number in such as -3

y = -(-3) - 3
y = 3 - 3
y = 0

Likewise, if you plug in a negative number for x, do recall the rule that a negative number times a negative number gives you a positive number then you subtract 3.
