Time to apply!!! Tristan buys a computer for $2100. For tax
purposes, he declares a linear depreciation (loss of value) of $700 per year. Let y be the declared value of the computer after x years. What is the slope of the line that models this
depreciation? Find the y-intercept of the line. Write a linear equation in slope-intercept form
to model the value of the computer over time. Find the value of Tristan’s computer after 2.5 years
