Explanation:</h2>
In order to solve this problem, let's remember the point-slope form of the equation of a line:
We know two points:
So:
So this is a constant line (slope equals zero). Therefore, every point has a y-coordinate 
. In other words, the equation is:

In more conventional notation, ...
b(x) = -15x² +450x +325 . . . . 0 ≤ x ≤ 24
For 1990, x = 1990 - 1983 = 7
b(7) = -15·7² +450·7 +325 = 2740
The value of the card in 1990 was 2740.
