Algebra help please?
Compare and contrast these four functions using complete sentences. Focus on teh slope and yintercept first, and then on any additional properties of each function.
I alread have some of it, but I need some help.

Best ResponseYou've already chosen the best response.0I already have that f(x) = 2x + 5 and it gives me j(x) = 2x  5. I think g(x) = 4x  8 and h(x) = 2x  1 but I'm not sure of those two are correct.

Best ResponseYou've already chosen the best response.1for h(x) line is increasing or decreasing ?

Best ResponseYou've already chosen the best response.0It's starting at the five and going over 1 and down 2. I don't know how to write that though.

Best ResponseYou've already chosen the best response.1so what does it means ?

Nnesha

Best ResponseYou've already chosen the best response.1nope if line is decreasing then slope would be negative

Best ResponseYou've already chosen the best response.0Oh yeah, so it'd be 1/2?

Nnesha

Best ResponseYou've already chosen the best response.1nope 2 is right slope is rise over run = 2/1 =2 it's decreasing so would be negative

anonymous

Best ResponseYou've already chosen the best response.0Oh okay. So the function would be h(x) = 5x  2?

Best ResponseYou've already chosen the best response.1hmm yintercept is a point where line intersect yaxis y=mx+b where m is slope b is yintercept

anonymous

Best ResponseYou've already chosen the best response.0y = mx + b sooo h(x) = 2x + 5

Best ResponseYou've already chosen the best response.0Okay, thank you. Now what about the g(x) function. Did I get that equation right?

Best ResponseYou've already chosen the best response.1nope slope and yintercept both are wrong try again show ur work so i can find out the mistakes :=)

Best ResponseYou've already chosen the best response.0Well I said it was g(x) = 4x  8 because under the x column it is increasing by 4 and under the g(x) colume it is increasing by 8.

Best ResponseYou've already chosen the best response.1x isn't increasing by 4 would you add 4 with 2 to get 2 ?

anonymous

Best ResponseYou've already chosen the best response.0Yes... 2 + 4 = 2 then 2 + 4 is 6

anonymous

Best ResponseYou've already chosen the best response.0Even my calculator says that 2 + 4 is 2

Best ResponseYou've already chosen the best response.1hmm that's not a good way to find slope you should use slope formula

Best ResponseYou've already chosen the best response.0g(x) is increasing by 8 though. 1  8 = 9 and 9  8 = 17

Best ResponseYou've already chosen the best response.1that's not right slope isn't 4 use the slope formula \[\huge\rm \frac{ y_2 y_1 }{ x_2 x_2 }\]

Best ResponseYou've already chosen the best response.0I don't have coordinates so I can't use that formula.

Nnesha

Best ResponseYou've already chosen the best response.1that's the difference of y's and x's y's =8 x's = 4

Nnesha

Best ResponseYou've already chosen the best response.1so replace y_2 y_1 = 8 and x_2  x_1 =4 that would give you slope

Best ResponseYou've already chosen the best response.1you can use the table to find slope (2 ,1)(2,9)(6,17) are coordinates

Best ResponseYou've already chosen the best response.1slope formula is \[\huge\rm \frac{ difference~of~y }{ difference~of~x }=\frac{ y_2y_1 }{ x_2x_1 }\]

anonymous

Best ResponseYou've already chosen the best response.0Oh! Okay so... y2  y1 / x2  1 9  (1) / 2  (2) = 8 / 4 simplified would be... 2

Nnesha

Best ResponseYou've already chosen the best response.1and you said x is increasing by 4 and y increasing by 8 that's difference between y and x's \[\huge\rm \frac{ difference~of~y }{ difference~of~x }=\frac{ y_2y_1 }{ x_2x_1 }=\frac{8}{4}\]

Best ResponseYou've already chosen the best response.0Now how do I figure out my yinercept? Do I just use 8? So my function would be: g(x) = 2x  8

Nnesha

Best ResponseYou've already chosen the best response.1nope use on of the order pair (x,y) plug that into the equation y =2x+b

anonymous

Best ResponseYou've already chosen the best response.0So my function is g(x) = 2x  5, right?
