For a good time, solve this shmoopy question...
- 00:05
What is the slope of a line with the equation 4x plus 2y equals 12?
- 00:12
And here are your options...
- 00:16
Okay, when in doubt put the equation into the standard point slope form of a line
- 00:21
We want the Y over here and the left in the

X over here on the right. So we can rewrite the equation
- 00:29
as 2y equals -4x
- 00:32
plus 12. We just subtracted 4x from both sides
- 00:37
Now we need Y, not 2y, on the left dividing both sides by two
- 00:42
and we have Y equals -2x plus six
- 00:46
so the slope here is M which is...yeah negative 2 and the answer is A.
