1) A railway system on a hillside moves passengers at a constant rate to an elevation of som. The elevations of a train are given for two different locations:
Time (seconds)

14.5
42
Height (meters)

9

20
Part A Write an equation in point-slope form to represent the elevation of the train in
terms of time. How can you use the equation to find the rate of increase in elevation
of the train in meters per second.
Part B At what elevation does the train start initially? Write a linear equation in a
form that gives the information as part of the equation. Explain your reasoning.

Need on this geometry question. explain how you did it.
