The weight of a person on or above the surface of the earth varies inversely as the square of the distance the person is from the center of the earth. a particular person weighs 192 pounds on the surface of the earth and the radius of the earth is 3900 miles. determine the equation that relates weight, w, to the distance from the center of the earth, d, for this person.
answer choices on picture.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
