And here's a shmoopy question for your brain.
- 00:05
If the linear equation y = mx + b, with m = -0.2, was graphed on coordinate axes...
- 00:12
...the graph would look like which of the following lines?
- 00:16
And here are the potential answers -- all graphs...
- 00:19
Try it yourself first.

So... there's really one thing this question is asking: Do you know m?
- 00:27
Yeah, m. The letter.
- 00:30
Well, it means slope in our little graphy world here -- it is
- 00:34
a calculation of rise divided by run...
- 00:37
...and there are really 4 prime time versions of m.
- 00:40
If m is flat, like this, slope is 0.
- 00:44
If m is vertical like this, slope is undefined -- yeah, you can't divide by 0.
- 00:49
If m is shaped upwards like this, m is positive.
- 00:52
And if m is shaped downwards like this, m is negative.
- 00:55
In this case m is negative so there's only one graph it could... be. which is... B. Done.
