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

00:25

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
