so his problem who want to find the equation mackenzie one those tickets to
the graphite looks cute
it also parallel seized three x months why months for equal zero
if they're to be parallel
than what we need to is we need the slope
of this line 'cause we need to know what the slope of
this one's going to need to be so let's start off by the finding that slope
easiest way to do that is to get this into
slope intercept form
basically solve it for a while
so i can do that real quick
by adding wire to both sides
the negative reacts minus four
people's lives
and i now have my m
bmx was before
there's slopes and that's the slope of attendant line
because there was a parallel to the speed of light
now
went on the insulin
satisfied it into line member we need to think swings local appointed a concert
now to find the slope of attention line well we needed to repetitive of our
function
so we need
why primal call it
or ecology why d_x_ whatever notation you like
here we have a power function
so using our power walk rule
wipro and as equal three x squared
now we know that we want
three x squared to be equal to
were basically giving our she was slow pace people to each other
now the reason i'm doing this is we have to find out the points
y equals execute
where the slope is going to be three
now if i saw this data by both sides by three
negative squared equals one
square root
both sides and i'm going to get x equals not just one
but it could be plus or minus one
so that tells me that on the graph of wipo's execute
there two places
but it was an absolute three-quarter positive one wanted negative work
so if we want to take a look at what's going on here
let's put it in a graphical for equals thanks to you
there with me this is a hand-drawn graph
so we really wanted to find here
they were in other words
over here
so we're actually going to have
answers to this problem
one with an excel you've positive one
and one with an expiry of negative one
two things we need to find potential client or any linear function the slope
at a point that it goes for
we are denoted slopes for both lines history
and we know the expel used for both lines
one of them is one the other one is negative one
now what we need is the wide-eyed
or we go back to the original function for that
so why do you calls
positive one cute which is one
slick gives us this why value
so we need to read
never point we have our slope
what's goin do some quick slope form wide myers the white ***
equals slope
times x minus the expel you
and that's our look
now if we wanted to convert this to slope intercept form
we distributed three
so i guess if three packs
minus three
and then we had one to both sides
so one of our change alliances line three x
minus two
we have one more extensive wine coming
it also has the slope of three
now it's kind of extra you've negative one
script with that and excuse a negative one cute
his negative one
some negative one negative one
will do this one
staring off into slope intercept forms you can see the difference
in this case would start to set up by equals three
explicit d and i were employed in this point
figure out will be should be
we know that when why is negative one
extended warranty
so negative one people's negative three-plus b
there's been a lot of symmetry here
had three to the science
intricate
geet
equals too
so the other solution is why equals
three tax
close to it
sarah marcus that were destroyed
three explosive
and their car
parts used against blacks
