PLEASE HELP!

OpenStudy (xmissalycatx):

With?

OpenStudy (znappydooz):

Compare and contrast these four functions using complete sentences. Focus on the slope and y-intercept first, and then on any additional properties of each function.

OpenStudy (znappydooz):

Could u help me @jigglypuff314?

jigglypuff314 (jigglypuff314):

Let's try to figure out the slopes and y-intercepts for each function first :) do you know how to do that? ^_^

OpenStudy (znappydooz):

h(x) y = 5 g(x) y = -5 j(x) y = -5

jigglypuff314 (jigglypuff314):

how about for f(x) ? :) hint: y intercept is the "starting point" before anything else is added or subtracted

OpenStudy (znappydooz):

Would f(x) = 2x + 5? x is the amount of time he walks the dog, 5 is the 5 dollars he started with from his dad and 2 is the amount of dollars he gets every time he walks the dog.

jigglypuff314 (jigglypuff314):

^ that's perfect ^_^

OpenStudy (znappydooz):

Alright, so we got that part down :P

jigglypuff314 (jigglypuff314):

aye next part is slope :P

OpenStudy (znappydooz):

h(x) = 1/-3?

jigglypuff314 (jigglypuff314):

hmmm not quite? try using the points (0,5) and (2,1) to find the slope of h(x) :)

OpenStudy (znappydooz):

well, x goes up by 1 as y goes down by 3...

jigglypuff314 (jigglypuff314):

are you sure it's 3 ?

OpenStudy (znappydooz):

Oh, sowy its 2 XD

OpenStudy (znappydooz):

h(x) = 1/-2 or (1, -2)

jigglypuff314 (jigglypuff314):

mmm still be careful |dw:1449160939298:dw||dw:1449160990368:dw|
