can u find the slope

godlovesme · Answer

$$y2-y1/x2-x1$$

anonymous · Answer

ok I have a question, when it asks for that does it want like half of it? so their 8 lbs apart. so half of that would be 126 lbs? Am I on the right track with it??

anonymous · Answer

Agree with @Godlovesme, to find it at 5 years you have to find the rate of growth

godlovesme · Answer

i should look like this 
124-116/ 4-2 --->  8/2 --> 4 
u forgot to divide it by 2 @Tallan

anonymous · Answer

124 - 116/4-2 = 8/2 = 4
132-124/6-4 = 8/2 = 4
140-132/8-6 = 8/2 = 4
148-140/10-8 = 8/2 = 4

?I'm there!! I'm totally there!

anonymous · Answer

continue @Godlovesme

godlovesme · Answer

loll ;D 
@Tallan  got it?

anonymous · Answer

now we know we have a linear model!

anonymous · Answer

So it would be B right?

godlovesme · Answer

yep :)

anonymous · Answer

and we also know the slope!

anonymous · Answer

m = 4

anonymous · Answer

ok

anonymous · Answer

Hey, I am not taking this away from @Godlovesme

godlovesme · Answer

lol i gave u the medal :) @BPDlkeme234

anonymous · Answer

are you sure? @Godlovesme , I can leave it with you or provide hint!

anonymous · Answer

hint y = 4x +108

godlovesme · Answer

yes and god job setting up the actual eqn

anonymous · Answer

tnx @Godlovesme

godlovesme · Answer

np

anonymous · Answer

so, the person still needs the answer, i.e. substitute x=5, take it away @Godlovesme

anonymous · Answer

The answer would be B 128 lbs

godlovesme · Answer

he/she already got the answer though @BPDlkeme234

anonymous · Answer

cool! great job @tallan and @Godlovesme

anonymous · Answer

im a he :P @Godlovesme

godlovesme · Answer

thx for the medal guys ^.^
lol @Tallan  xP

anonymous · Answer

P.S. Derivation of the equation was simple: y-y1 = m(x-x1), you already gave me the slope!

anonymous · Answer

lol :P

anonymous · Answer

Tallan has a sense of humor, I like that!

anonymous · Answer

I try! xD

godlovesme · Answer

;D lolz i'm leaving dont forget to close the question :p @Tallan
