Which of the following linear equations corresponds to the table above?
O A. y = 4x - 3
O B. y=1/4X-3
OC. y="/4x+3
OD. y = 4x + 3

okay wait before i answer, is this for your points on a graph?

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
