# How do you graph #4x+y=-1# using intercepts?

##### 1 Answer

Sub in the variables as

In this case,

#### Explanation:

All we have to do is sub in the variables as

Here, we are solving for the

#4x+y=-1#

#4x+0=-1#

Now, let's bring like terms together and add them.

#4x=-1#

Now, we can isolate for

#(4x)/4=-1/4#

#x=-1/4#

Therefore, because

Now, if we're solving for the

#4x+y=-1#

#4(0)+y=-1#

Now, we add like terms,.

#y=-1#

Therefore, because

We can double check our work by graphing the equation:

graph{4x+y=-1 [-10, 10, -5, 5]}

As you can see, the intercepts on the graph match with what we solved for!

Hope this helps :)
