n is the m:n ratio
AlexandervonHumboldt2
  • AlexandervonHumboldt2
\[y=\frac{ my_2+ny_1 }{ m+n }\]
GabeBae
  • GabeBae
ooh
GabeBae
  • GabeBae
can you give me an example to solve?
AlexandervonHumboldt2
  • AlexandervonHumboldt2
use formula: \[[\frac{ mx_2+nx_1 }{ m+n }, \frac{ my_2+ny_1 }{ m+n }]\]
AlexandervonHumboldt2
  • AlexandervonHumboldt2
we have (x1,y1) = (-1,2) (x2,y2) = (4,-5) m:n = 2:3
AlexandervonHumboldt2
  • AlexandervonHumboldt2
plug in and solve
AlexandervonHumboldt2
  • AlexandervonHumboldt2
in our case (x1, y1)=(-3, -3) and (x2, y2)=(2, 4) i guess
GabeBae
  • GabeBae
\[\frac{ 2(4)+3(1)}{ 2+3 } , \frac{ 2(-5)+3(2)) }{ 2+3 }\]
AlexandervonHumboldt2
  • AlexandervonHumboldt2
yeah
AlexandervonHumboldt2
  • AlexandervonHumboldt2
i got the same
AlexandervonHumboldt2
  • AlexandervonHumboldt2
wait
AlexandervonHumboldt2
  • AlexandervonHumboldt2
the point is -1, not 1
AlexandervonHumboldt2
  • AlexandervonHumboldt2
it should be 3*(-1), not 3*(1)
GabeBae
  • GabeBae
sorry
GabeBae
  • GabeBae
Is the final answer 1, -0.8
AlexandervonHumboldt2
  • AlexandervonHumboldt2
yeah
AlexandervonHumboldt2
  • AlexandervonHumboldt2
now do that same with our points.
GabeBae
  • GabeBae
-1.08?
AlexandervonHumboldt2
  • AlexandervonHumboldt2
i got -1.25
GabeBae
  • GabeBae
how? o.o
AlexandervonHumboldt2
  • AlexandervonHumboldt2
i mean for your problem
AlexandervonHumboldt2
  • AlexandervonHumboldt2
not for the example
GabeBae
  • GabeBae
what would the answer be for the example
AlexandervonHumboldt2
  • AlexandervonHumboldt2
(1, -0.8)
GabeBae
  • GabeBae
why is the answer a decimal in the question they gave me
AlexandervonHumboldt2
  • AlexandervonHumboldt2
because you need to find only y point
GabeBae
  • GabeBae
oooh ok makes sense
GabeBae
  • GabeBae
how about this one?

AlexandervonHumboldt2
  • AlexandervonHumboldt2
how you got 1.5?
GabeBae
  • GabeBae
Is it the same thing as the previous question?
AlexandervonHumboldt2
  • AlexandervonHumboldt2
yeah
GabeBae
  • GabeBae
okay thank you that's all I needed help on :')
AlexandervonHumboldt2
  • AlexandervonHumboldt2
ok
AlexandervonHumboldt2
  • AlexandervonHumboldt2
