The number of people employed in a country as solar photovoltaic installers was 14,000 in 2019. By 2029, this number is expected to rise to 20,500. Let y be the number of solar photovoltaic installers employed in the country in the year x, where x = 0 represents 2019. Use this to answer parts a and b. a. Write a linear equation that models the number of people employed as solar photovoltaic installers in year x. [Hint. The line must pass through the points (0, 14000) and (10,20500).] y =_ (Type your answer in slope-intercept form. Use integers or decimals for any numbers in the expression.) b. Use this equation to estimate the number of people who will be employed as solar photovoltaic installers in the year 2028. people (Type a whole number.)
