A scuba diver dives to 180 feet below sea level. The liner equation -60x + 2y= -360 represents his trip back to the surface. The variable y is his elevation in feet relative to sea level after x minutes. Graph the equation.

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
