1. Right triangle ABD is congruent to right triangle CBD. Name the theorem or postulate that justifies the congruence.

i believe that the slope of the line is -5

step-by-step explanation:

the answer for this is 0.25 km. : )

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
