- . Due to erosion, a river shoreline is losing several thousand pounds of soil each year. A linear equation that expresses the total amount of soil lost per year is y = 12,000x. What are the independent and dependent variables?arrow_forwardStudents at Tahayghen Secondary School sell punch during the school carnival. The number of cups sold, n, is a linear function of the temperature in degrees Celsius, t. The students sold 458 cups when the temperature was 25 °C. They sold 534 cups when the temperature was 29 °C. a) Write an equation in slope-point form to represent this function. b) Use the equation in part a to determine the approximate temperature when the students sell 325 cups of punch.arrow_forwardLet �(�) be the height of a maple tree in inches and � the number of years since 2000.
