Question 131728: The word problem is this:
Suzanne had 9 CDs. She decided to add CDs to her collection at the same rate each week. After 2 weeks, she had 15 CDs.In how many weeks did she have 27 CDs? How many CDs did she have after 8 weeks?
MY daughter plotted it out on a graph and came up with (0,9) (2,15) (6,27) and (8,33) Which would mean that she had 27 CDs in 6 weeks and 33 CDs in 8 weeks.
And then she was asked to write an equation for this word problem
Her answer was : Y= 9+2X
Could you please tell me if this is correct?
Thank You

Question 136348: Find an equation in slope-intercept form passing through the points (-6.2,18.1) and (-3.4,18.1).
I am not too sure of how to set up the equation. Here is what I think it should be.
m = y2 - y1/x2 - x1
m = 18.1 – 18.1/3.4 – (-6.2)
