Question

The value of a collectible coin can be represented by the equation y=2x+9.74, where x represents the number of years that Consuelo has owned the coin and y represents the total value, in dollars, of the coin. What was the value of the coin when Consuelo originally purchased it?

Answer 1

9.74

Explanation:

9.74 in the equation represents b which is also the initial value. The initial value is when Consuelo originally purchased it.

Thus, it is 9.74

Answer 2

when Consuelo first purchased x = 0 because x represents how many years he has owned it for.

plug 0 into the equation for x

y = 2x + 9.74
y = 2(0) + 9.74
y = 9.74
