Rich is standing in the Rosemont Valleyat an elevation of 120 feet above sea level. The change in elevation in the Rosemont Valley follows a linear relationship such that for each step forward Rich takes, his elevation increases by foot.

If x represents the number of steps forward Rich has taken and y represents his elevation, which equation could be used to represent this linear relationship?
A. y = 120x +
B. y = x − 120
C. y = x + 120
D. y = 3x + 120
