HI!!

Hi!

that would be -4+4 over 9+4 right?

not quite

you want to subtract, not add

Oh, okay. Hold on Lemme try.

kk

ok so its -8/5 ??

hmm \(9-6=?\)

oh dang! I was doing -4. My bad. So it's 4.

lets go slow

Yes

(9, -4) and (6, 4)

first we do it the think way, then we do it the math teacher way

Okay, it's like the third day of school. My brain doesn't work yet! sorry ahah.

okay, yes.

okay, got it.

who goes to school in the middle of august?

Everyone where I'm from starts in August. I know some places in California start later.
so y=mx+b?

wait, thats not right.

no that is the "slope intercept " form we are not there yet

y-y1 = m (x-x1)

yeah that one

Okay so
-4 - 4 = -8/3 (9 - 6) ?

ooh no

you put numbers everywhere

oh. gosh ok.
y+4= -8/3 (x-9)

looks a lot better now

subtracting a negative turns it into an addition basically, right?

right

now you should probably put it in "slope intercept" form aka solve for y

you know how to do that? takes the same two steps every time

Move the 4 to the other side?

no not yet

first distribute the \(-\frac{8}{3}\) on the left

oh yeah. so I multiply it or add it to the left?

multiply

\[y+4=-\frac{8}{3}+24\] if my arithmetic is correct

then don't "move the 4" subtract 4

sorry, typo there i meant \[y+4=-\frac{8}{3}x+24\]
i dropped the x by mistake

wait, where did 24 come? distributing the slope on the right side?

yeah

cancel the 3's

\[-\frac{8}{3}\times (-9)=3\times 8=24\]

Okay, I understand.

so now we are at
\[y+4=-\frac{8}{3}x+24\] subtract 4 from both sides and you are done

y=-8/3x+20

yup

took a while but i hope it is ok

Is that the final answer?

Thanks by the way (:

yeah it is the "final answer" as they say on tv you are quite welcome \[\color\magenta\heartsuit\]

haha, of course! I'll give you a medal.

thanks!
