Answer:
The y-intercept represents the price of the computer last Monday.
Step-by-step explanation:
The y-intercept is the point on a graph where x equals zero. Also, the y-intercept is the output value in an equation when x equals zero.
In this situation, x represents the number of days since last Monday. So, when x equals zero, no time has passed.
Therefore, the y-intercept represents the price of the computer last Monday.
