Part A: Describe the relationship between the temperature of the city and the number of cups of lemonade sold. 
Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept.

@awesomepuppies , @dan815  , @whpalmer4       could any of you help please?

I think A is                                                                                                                            A. The relationship between the temperature of the city and the number of lemonade sold would both be increasing.

wouldn't a clearer way to state that be that lemonade sales increase as temperature increases?

anonymous · Answer

Yes, thank you @whpalmer4

whpalmer4 · Answer

which points will you use for part B?

anonymous · Answer

4, 8, 16, and 20

whpalmer4 · Answer

those are not points.  points have two coordinates on a two-dimensional graph like this.  (x,y)

whpalmer4 · Answer

or in this case, (F, cups)

whpalmer4 · Answer

you want to pick two points, one at each end, where a line through them indicates the overall trend

anonymous · Answer

4,30 and 20,90

whpalmer4 · Answer

no, wrong order, and no parentheses.  try again

whpalmer4 · Answer

(F, cups) is how points on this graph are described
