Thank you We sneak in and here's your shmoop twos
- 00:05
You're brought to you by negative slopes which are awfully
- 00:08
hard to ski on gravity to work there Art If
- 00:12
a line has a slope of negative seven and it's
- 00:14
equation could be written why equals five minus blank x

Okay what is this question i want to know Well
- 00:27
we're giving the equation for a line most of one
- 00:30
anyway and we need to figure out what coefficient should
- 00:33
go before the x to give us a slope of
- 00:35
negative seven You might want to breathe a sigh of
- 00:38
relief right now because this one's pretty simple we don't
- 00:40
need to graph anything no combining like terms under that
- 00:43
business All we have to do is recognize that when
- 00:46
we have an equation written in this form the coefficient
- 00:49
of x is the slope In other words we just
- 00:52
plug in a seven The only potentially tricky part is
- 00:55
that we can't get sloppy and ignore the minus sign
- 00:57
in there We want a slope of negative seven so
- 01:00
we only need to put a regular old seven in
- 01:02
the blank and the minus sign alternate negative for us
- 01:05
If we plugged in negative seven the signs would cancel
- 01:09
and we'd be left with a slope of positive seven
- 01:11
which we don't want to Our answer is seven which 00:01:16.474 --> [endTime] incidentally is also a difficult thing to scheme
