Transcript

00:02

Okay more matthew drills Here we go What is the

00:04

slope of the line X equals for why minus one

00:13

All right Come test day You better be prepared to

00:16

work with slope Future real world applications might include designing

00:20

a ski slope in the middle of a dubai shopping

00:22

mall Yeah there it is That's a real thing They

00:25

even desert people need a little icy fun every now

00:27

and then To find the slope of a line we

00:29

need to first put the equation of the line into

00:31

the slope Intercept former y equals mx plus b and

00:35

check your body somewhere You've probably tattoo that on there

00:38

by now See how why is hanging out alone on

00:41

one side of the equation All only sad there moby

00:44

kind of Well that's what we're aiming for So start

00:46

by isolating why First add one to both sides and

00:49

we get x plus one is four Why And we

00:52

divide both sides by four So that gets us Why

00:55

equals one fourth Acts plus 1 fourth All right Well

01:00

now that we've isolated why we're looking at a linear

01:01

equation in slope intercept form We know exactly what makes

01:05

these things tick Well the slope of the line is

01:08

given by the coefficient of the ex term representing our

01:11

slope intercept equation by m So in this case the

01:14

slope is right there Right in your face One fourth 00:01:16.975 --> [endTime] x That's it The answer is d fourth
