A boy is 4ft tall standing in front of a tree that is 24ft tall. If the tree cast a shadow that is 18ft long on the ground and two shadows end at the same point, what is the length of the boys shadow?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

i believe the correct answer is b.

yes.. it's proven to be 36.
