BRAINLIEST IF U ANSWER The value of a baseball player's rookie card began to increase once the player retired. When he retired in 2000 his card was worth $4.23 The value has increased by $2.92 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y proportional? What was the value of the card in 2010 ?

Relationship:

They are not proportional

The value is $33.43

Step-by-step explanation:

Given:

When he retired, the expression is:

and the rate (m) is:

Solving (a): The relationship between y and x

This can be solved using the following point-slope formula:

Substitute values for x1, y1 and m

Make y the subject

Solving (b): Are they proportional?

No, they are not

A proportional relationship is expressed as:

By comparing this to ; they have different format

Solving (c): Value in 2010?

First, we determine the value of x in 2010

2000; x = 0

2001; x = 1

-

2010; x = 10

Substitute 10 for x in

828. all there is to it!
