The value of a collectible coin can be represented by the equation y=2x+9.74, where x represents the number of years that Consuello has owned the coin and y represents the total value, in dollars, of the coin. What was the value of the coin when Consuello originally purchased it?
y = 2x + 9.74 x = number of years owned y = total value in dollars
y = 2(0) + 9.74 y = 9.74 Substitute x with 0 because the question asks what is the value of coin when consuelo originally purchased it. So, at the time of purchase it's been 0 years since he owned it.
