****Quick question. Point-Slope. Thanks!**

## Homework Statement

Ok i get all of it, except that last part. Here ill show you. Point-Slope question.

(4, -3), m = -2

so....

y + 3 = -2(x - 4) which then becomes y+3 = -2x + 8)

Then...

subtract 3 from y + 3, and then do it on other side

which then gives you:

y = -2x + 5

Now, I dont get this final part. It says that you go y + 2x, and then -2x + 2x

which gives you: 2x + y = 5

I dont get why and how you do that last part? Can anyone please explain?
