Tell whether the function is a proportional relationship. y = 3x

OpenStudy (anonymous):

OpenStudy (anonymous):

This is confusing me.

OpenStudy (anonymous):

plug in zero of x and then y to find the points

OpenStudy (anonymous):

@connor_ do you understand?

OpenStudy (anonymous):

@chinenyeogueri No, I don't.

OpenStudy (isaiah.feynman):

Okay connor just like mertsj said, is it in the form y=kx?

OpenStudy (anonymous):

@Isaiah.Feynman I'm not really sure.

OpenStudy (anonymous):

so if x=0 what would y be if you plug it in the equation and if y=0 what would x be if you plug it in the formula

OpenStudy (anonymous):

Umm, 0?

OpenStudy (isaiah.feynman):

|dw:1387076114398:dw|

OpenStudy (anonymous):

@Isaiah.Feynman So, is it a proportional relationship and a correct answer?

OpenStudy (anonymous):

@Isaiah.Feynman What does it shows "y = kx"?

OpenStudy (isaiah.feynman):

Yes sir, its obvious the two equations have the same form.

OpenStudy (anonymous):

@Isaiah.Feynman I mean't, why does it shows "y = kx"?

OpenStudy (isaiah.feynman):

That's the form of tyour equation

OpenStudy (anonymous):

@Isaiah.Feynman Hmm, okay. I guess. But thank you though! (:

OpenStudy (anonymous):

how does answer have to look like? a graph?? @connor_

OpenStudy (anonymous):

@chinenyeogueri No I mean't, I brought up the graph because it's used for graphing.

OpenStudy (anonymous):

well do you graph 2 lines

OpenStudy (anonymous):

@chinenyeogueri Only one.

OpenStudy (anonymous):

ok yeah but you were right with 0 but what is the 0

OpenStudy (anonymous):

@chinenyeogueri What do you mean? In the graph?

OpenStudy (anonymous):

so you plug in 0 for x and got y =0 so the first point on the line is (0,0)

OpenStudy (anonymous):

@chinenyeogueri Hmm okay. But are you talking about the "0" in the graph because that's the letter "O"

OpenStudy (anonymous):

im talking about the number 0.....
