Transcript

00:02

Okay sy mash members we got a pretty colored graph

00:05

for you here It's like the rainbow star What do

00:07

you think Signing it up ok which of the lines

00:10

shone above Has the smallest slope Don't throw your hands

00:20

up in the air just yet you know the kind

00:22

where you're in despair or the kind where you just

00:24

don't care As it turns out we don't actually need

00:26

to calculate each slope and then compare numbers We just

00:30

need to remember to basic principles First lines with a

00:33

positive slope extend upward into the right lines with a

00:37

negative slope extend downward into the right Negative numbers are

00:41

smaller than positive numbers so we're going to rule out

00:45

a c and line d here which have positive slope

00:48

and second lines that extend upwards Mohr steeply or closer

00:52

to the vertical access have a larger slope right it's

00:56

a higher number at least a larger absolute value Well

00:59

this gets tricky with negative numbers because negative numbers with

01:02

a larger absolute value are actually smaller For example negative

01:06

eight has a larger absolute value than negative one What

01:10

line b has a negative slope with a larger absolute

01:13

value than that of line eh So line b has 00:01:17.27 --> [endTime] the smallest slope so yeah the answer is b
