Answer:

The value of the coin when Consuelo originally purchased it is $9.74 ⇒ C

Explanation:

The form of the linear equation is;

y = m x + b, where

  • m is the slope of the line (The rate)
  • b is the y-intercept (initial amount, value y at x = 0)

∵ The value of a collectible coin can be represented by the equation

y = 2 x + 9.74

→ Compare it with the form of the linear equation above

m = 2

b = 9.74

x represents the number of years that Consuelo has owned the coin

y represents the total value, in dollars, of the coin

→ That means the value of y at x = 0 is the value of the coin when

Consuelo originally purchased it

∵ b represents the value of y at x = 0

∵ b = 9.74

The value of the coin when Consuelo originally purchased it is $9.74
