Last week, Hazel paid $32 to have $40 reports printed. This week, she paid $57 to have $100 printed. Assume the relationship is linear.
Which equation models the relationship between the numbers of reports,x, and the cost, y?
*PLEASE EXPLAIN, because I keep getting the same answer but it's not one of the choices.

basically, you want to write two points 

(40,32) and (100,57)

and write an equation for those two points

vocaloid · Answer

what have you done so far?

anonymous · Answer

that's the thing, i can't find my answer in the multiple choice.

vocaloid · Answer

what did you get as your answer?

anonymous · Answer

y=2x-14

anonymous · Answer

arn't you suppose to write the slope

vocaloid · Answer

I think you switched x and y when you were writing your equation

vocaloid · Answer

x = number of reports
y = money

anonymous · Answer

i dont get it, sorry.

vocaloid · Answer

slope = (57-32)/(100-40)

anonymous · Answer

all the answers are in multiple choice. and they're all in slope-intercept form. and my answer, that i've redone a bunch of times now, is the same but it's not one of them.
