4.) In 2018, Arya bought a Gaming laptop for $5,000. Say the PC depreciated linearly to a value of $0 over 8 years as the latest assessment. This means, we can model the value of the PC with a linear function. Use the function to determine the value of the gaming computer after 6 years after the last assessment on the car. a.) Johnny says the following is the correct model. If you disagree, write the correction and what the actual model should be. If you agree, justify each of his steps. Step 1: This creates the points (0, 5000) and (8,0) Step 2: m = 5000 0 0-8 5000 8 625 Step 3: P() - 625t +5000 Step 4: P(6) - 625(6) + 5000- 3750 + 5000 = 1250
