Esmeralda collected data about the number of compact discs (CDs) sold at a music store during part of the 1980s and early 1990s. An equation for the line of best fit for the given data is
y = 518x - 43886 where x = 0 means the year 1900. The point (88, 1497) was one of the points.

What is the difference between the observed value and the predicted value at x=88?
A. 201
B. 518
C. 979
D. 1698

vocaloid · Answer

to find the "predicted value", use the equation

y = 518x - 43886

when x = 88, what does y equal?

Honestly I have no idea

vocaloid · Answer

"x = 88"

means we can replace "x" with "88" when we see x

vocaloid · Answer

so what does y = 518x - 43886 equal?

I have no Idea man I just need the answer to this

vocaloid · Answer

if x = 88

what is 518*x?
