I need to know which one i put as x and y to make a line graph?

the flower power has offered to sell its roses for a fixed down payment of $60 and an addition charge of $.50 per stem.





tell me if i am right but is the # of roses should be in the x place and the price of the roses should be in the y place?

You are correct. The number of flowers is the independent variable, which is placed on the x-axis. The price is dependent on the number purchased, so it goes on the y-axis.
Reply:I think that the number of roses should be on the y (or bottom, horizontal part of the graph. The x (vertical) graph in this case should begin with the $60 as a straight line across the graph and the different prices related to a spot on the graph for the various number of roses. At least that is what I would do. But, it is not set in stone, if you want to be creative.
Reply:your right because the x axes is the independent variable and the y axes is the dependent variable.
Reply:correct
Reply:Not to confuse you, but you can either make x or y. your formula can be y = $.50x + $60 where x is the number of roses and y is the total dollars spent. OR your formula could be y = (x-60)/.5 or y = 2x-120 where x %26gt;= $60 and y is the number of roses.
Reply:u r rite
Reply:You are absolutely right. # of roses is the independent variable and as such goes on the x-axis
Reply:Yes. Sounds right. One rose would cost $60.50? Two roses would be $61.00? Is that right? A dozen would be $66.00.
Reply:You're right.
Reply:Correct ‼
Reply:You're right! :)
Reply:Yes. So your y axis starts at $60, and then rises by 50c per stem (x axis).
