because the skis are on the snow it causes friction which turns in to heat causing the skier to stop
the height of the skier.
At the steepest point near the bottom of the hill
If you are on a skateboard going x miles per hour, and you come across a downhill slope, your velocity will increase as you go down the hill.
Half way down the slope, the skier has kinetic energy and potential energy. At the top of the slope, before he starts moving, he only has potential energy. At the bottom of the slope, he has only kinetic energy. This is an extremely simplified explanation, but it's probably the answer that your teacher is looking for. Hope that helps.
a skier going up a hill a skier going down a hill
If a line has a negative slope it is going 'down hill' and if it has a positive slope it is going 'up hill'
Once the skiers go uphill by a cable car or lift, they gain potential energy. This potential energy is converted into kinetic energy once the skiers start to ski down the slope.
The skier will gain momentum as they travel down the hill but once the hill flattens out they will eventually slow down due to friction

That will depend on what equations but in general if it has a slope of -3 then it will have a down hill slope
The line is going 'down hill' from left to right
At the steepest point near the bottom of the hill
At the top of the hill, the skier possesses potential energy. As he travels down the hill, his potential energy is converted into his kinetic energy. Conservation of energy says that the skiers potential energy equals his kinetic energy further downslope (plus a little lost to heat from friction).
