Question 130974: For what numbers x is f(x) = 0?
the graph is: its starts from -1 on the y-axis and cuts over 1 on the x-axis and ends at points (6,1.5)
it was solve before but the answer was not correct. the answer options are a=(-60,70) b=-60 c=(-60,70,100) d=(-100,-60), (70,100)

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 134369: I am very confused on how to find the slope. My problem is below. I have completed it all except for the slope. I think I am getting confused by the fraction?
a) Solve for y
Answer:y=-3/4x+2
Show your work here:3x-3+4y=8 8/4=2+(-3/4x)
b) When graphed this equation would be a line. By examining your answer to part a, what is the slope and y-intercept of this line?
Slope = ______
Y-intercept = _(0,2)____

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)
Thanks
