Question
Janet is training for a marathon. She decides to track her time per mile, in minutes, for 8 weeks. Which equation best fits the data?
A graph is labeled as Marathon Training. The horizontal axis is labeled as Weeks and the vertical axis is labeled as Time per mile left parenthesis minutes right parenthesis. The values on the horizontal axis range from 0 to 10 in increments of 2 and the values on the vertical axis range from 0 to 10 in increments of 2. Nine points are marked on the graph with their coordinates approximately equal to (0, 10), (1, 9 decimal point 9), (2, 9 decimal point 6), (3, 9 decimal point 5), (4, 9 decimal point 4), (5, 9 decimal point 2), (6, 9), (7, 8 decimal point 7), and (8, 8 decimal point 6).

So hard to read your posts!
instead of (3, 9 decimal point 5) why not just say (3, 9.5) ? etc
instead of
D.

why not just y = -2x - 8.6
I have no clue what procedure you have learned. Are you going
for a linear approximation, a quadratic or .... ?

I think these very strange math posts are the result of copying and pasting. Apparently something changed in Connections' website (programming) over last summer, such that students see math explanations and problems normally, but when they copy/paste, this nonsense happens. Students undoubtedly need to learn how to type their own instead of relying on copy/paste.
ooooooooooohhhhhhhhhhhhhhhh get him Wrieacher!
honestly i think Connections are try there best to prevent copy and paste now in most lessons you can copy any more and i think that the end goal
, the the programming was a last second resort for the lessons that dont have this fetcher.
