Answer 2

Answer 3

you should estimate the slope of this line.

Answer 4

well... umm i really have no clue :S

Answer 5

it looks like about 10

next, pick a point on the line, like (3,30)
find the equation of the line:
y - 30 = 10( x-3) or
y-30 = 10x -30
y = 10x

check, to make sure it makes sense: with x=1, y =10 which is a decent match

Answer 6

to find the slope, start at x=3, y=30 then count up 10 and over 1
the change is y is +10 and the change in x is +1 and the slope is 10/1 = 10

Answer 7

how much does it earn in its 8th quarter of operation?

use y=10x with x=8 to find y=80

Answer 8

yup :p

Answer 9

so its gonna be what (8,80) ???

Answer 10

or 80 for the 8th thing ?

Answer 11

I think they just want the y value (just the earnings)

Answer 12

ohh ok ! thank you!!!!
