alright so write point A and B in order pair A(? ,? ) point B( ? , ?) on the graph :-)
Nnesha
  • Nnesha
for example point A ( 0 ,0) so point B (? ,? ) ?
Spring98
  • Spring98
1,2
Spring98
  • Spring98
i mean (6,2)
Nnesha
  • Nnesha
yes right now use slope formula \[\huge\rm \frac{ y_2 - y_1 }{ x_2 - x_1 }\] plug in x and y values

12, and 4?
Nnesha
  • Nnesha
nope plug in x and y values how did you get 12 and 4 ?
Spring98
  • Spring98
i squared it
Nnesha
  • Nnesha
nope y_2 it is not square that's mean 2nd y
Nnesha
  • Nnesha
y_1 first y y_2 2nd y which is y_2 = 2 y_1 = 0
Nnesha
  • Nnesha
\[\huge\rm \frac{ 2-0 }{ 6-0 }\] like this x_1=0 x_2 =6 y_1=0 y_2 = 2
Spring98
  • Spring98
ok so how do i find the answer?
Nnesha
  • Nnesha
solve that
Spring98
  • Spring98
i don't know how to
Spring98
  • Spring98
it doesn't make sence to me
Nnesha
  • Nnesha
\[\huge\rm \frac{ 2-0 }{ 6-0 } = ?\]
Nnesha
  • Nnesha
why not ?
Spring98
  • Spring98
2/6
Nnesha
  • Nnesha
\[\huge\rm \frac{ y_2 - y_1 }{ x_2 - x_1 }\] formula to find slope between A and B point A(0,0) B(6,2) that's how i plug in x and y values now just solve reduce the fraction
Nnesha
  • Nnesha
2/6 reduce the fraction
Spring98
  • Spring98
1/3
Nnesha
  • Nnesha
yes right that's a slope of points A and B now find slope of points B and C just like did
Spring98
  • Spring98
there is only 3 left
Nnesha
  • Nnesha
what do you mean ?
Spring98
  • Spring98
there is only 3 left out of the numbers.
Nnesha
  • Nnesha
how do you know both didn't get same slope ?
Nnesha
  • Nnesha
point B is (6,2) what is point C (?? , ??)
Spring98
  • Spring98
oh sorry i got off track its (16,8)
Nnesha
  • Nnesha
yes right now find slope between B and C points use slope formula (6,2)(16,8) find slope
Spring98
  • Spring98
how do i do that?
Nnesha
  • Nnesha
just like we did for point A and B use that formula plug in x and y values
Spring98
  • Spring98
can you tell me how?
Nnesha
  • Nnesha
|dw:1433385627509:dw| now plug in numbers
Nnesha
  • Nnesha
ello what did you get ?? try it plz!
