There are 5 posts supporting the guardrail for the steps to your home. The tallest post is 3 feet tall. The heights of each post is 5/8 the height of the next larger post. Write an expression for the height of the shortest post. What is the height of the shortest post?

ok

step-by-step explanation:

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.
