Find the slope of the following equation. Simplify your answer.

5x + 2y = -10

to find the slope you will have to solve for y, so put 5x on the other side, to become 2y=-5x-10, the divide by 2, y=-5/2x-5, the slope would be down 5 over 2

y=mx+

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
