The function E = 8t +150, describes the elevation (E) that Rick hikes on a mountain and (t) is the amount of time in seconds. What does the slope mean and the y-intercept mean in this context?

The slope is 8 and it means that Rick is hiking down the mountain at 8 feet per second. The y-intercept is 150 and is the elevation at his starting point

The slope is 150 and it means that Rick is hiking up the mountain at 8 feet per second. The y-intercept is 8 and is the elevation at his starting point.

The slope is 8 and it means that Rick is hiking up the mountain at 8 feet per second. The y-intercept is 150 and is the elevation at his starting point.

The slope is 8 and is represents that amount of time Rick has been hiking the mountain. The y intercept is 150 and it is the total amount of time Rick spent hiking on the mountain.
