(15 points! ) the graph shows the distance a ghost crab can run over time the d equals the distance in meters and the t equal the time in seconds which is a direct variation equation for this relationship
a. d= 3/5t
b. d = 5/3t
c. t= 5/3d
d. t= 2/5d

Option B. d = 5/3t

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

d -----> the distance in meters

t ----> the time in seconds

Looking at the graph we have the point (3,5)

That means ----> For t=3 sec, d=5 m

Find the value of k

substitute the value of y and the value of x

The linear equation is

substitute the value of k
