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 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
