Which graph represents a proportional relationship?

Graph represented by option A.

Step-by-step explanation:

We are asked to choose the graph that represents a proportional relationship.

We know that a proportional relationship is in form , where k represents constant of proportionality.

We can see that graph represented by option A is the correct choice as the y-intercept is 0.

The equation of the graph represented by option A would be , where m represents slope of line.

Therefore, option A is the correct choice.

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
