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

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
