Carlota wrote the equation y + 2 = 2(x - 1) for the line passing through the points (-2, 1) and (1,7). Explain and correct her error.
Carlota's error is that she (select)
(select)
used the point (-2,1) instead of (1,7)
replaced x1 with y1
used the wrong slope

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+
