To predict the elevation level after skiing for 60 seconds, we need to substitute x = 60 into the linear model y = -30x + 6000 :
y = -30(60) + 6000
y = -1800 + 6000
y = 4200
Therefore, after skiing for 60 seconds, your elevation level would be 4200 feet.
You are snow skiing down a mountain that is represented by the linear model y=–30x+6,000 , where y is the number of feet after x seconds. Predict your elevation level in feet if you ski 60 seconds
