COLLEGE PREPARATION MATHEMETICS - TECHNICAL (MATOOM) 6. A mountaineer has reached the top ofa mountain. He then begins descending on foot with his altitude decreasing at a constant rate. The equation relating descending time and altitude can be written as A = mt + bwhere A is altitude and t is the number of hours spent climbing. After 2 hours of descending, he has reached an altitude of 545 m. After 5 hours, he has reached 350 in. These altitudes and times represent two points on the graph of the equation, A = mt+ b. Note: You may like to draw a quick sketch of these two points, (2, 545) and (5, 350), to help you answer this question. Your sketch will not be marked. a) Find the slope of this linear relation. b) In the context of this question, what the slope represent? c) Find the y-intercept. d) In the context of this question, what does the y-intercept represent? e) Write the equation of the line. f) Use the equation to determine the altitude of the climber after 7 hours of descending. 65 Marks MT4.1 ONLINE TEST A April 3, 2020
