Question 717373: I have been trying to figure this problem out for an hour. Please help. Ok so I have a graph and the problem reads, "the graph below represents the total number of times a certain website was visited over a 5-day period. So the left side of the graph represents the "number of visits to website" and the bottom side represents the "number of days". The left side goes in multiples of 20, so 0..20..40..60..80, etc. The bottom side goes in multiples of 1, so 1..2..3..4..5. The intersections are (1,30), (2,60), (3,90), (4,120), (5,150). The question is "write an equation that represents the total number of times this website is visited, v, after d, days. I have an equation of 1.5v+30=900, but I don't think it's right. Can you please help me figure this out? Thank you..

You can put this solution on YOUR website! I have been trying to figure this problem out for an hour. Please help. Ok so I have a graph and the problem reads,
----------------------------------------------
"the graph below represents the total number of times a certain website was visited over a 5-day period.
So the left side of the graph represents the "number of visits to website" and the bottom side represents the "number of days".
----------------------------------------------
The left side goes in multiples of 20, so 0..20..40..60..80, etc.
The bottom side goes in multiples of 1, so 1..2..3..4..5.
------------------------------------------------------------------
The intersections are (1,30), (2,60), (3,90), (4,120), (5,150). The question is "write an equation that represents the total number of times this website is visited, v, after d, days.
---------------------------------------
I have an equation of 1.5v+30=900, but I don't think it's right. Can you please help me figure this out? Thank you..

You have 5 points relating # of days and # of visits.
slope = (60-30)/(2-1) = 30
-------
Equation Form: # visits = (slope)(# of days) + b
Using the point (2,60) solve for "b":
60 = 30*2 + b
b = 0
-------
Equation:
v(d) = 30d
