Question 333998
can you explain how to do this its a linear equation 
y=-4-x+1
---
y = -x-3
---
Now, what do you want to do with it?
You could graph it:
Find two points-------
Let x = 0, then y = -3 giving you point (0,-3)
---
Let x = 2, then y = -1 giving you point (2,-1)
==================
Plot those points and draw a line thru them.
{{{graph(400,300,-10,10,-10,10,-x-3)}}}
======================
