Answer: 
Step-by-step explanation:
y=mx+b is the equation for a non-proportional relationship. Essentially, you can use this for a proportional relationship as well, since the y-intercept of a proportional relationship will always be zero. 
and 
are the variables of the equation, and represent the coordinates of the line. 
is the slope of the equation. To find the slope, use rise over run, or the change in y between two points over the change in x between two points. The last part is the y-intercept, or 
. This shows when the line intercepts the y-axis.
Answer:
$316.
Step-by-step explanation:
The terms that have n can be operated:
15n +12n + 100 = 27n +100. Then, we have that
total cost = 27n +100 for n skiers. So, for 8 skiers we have
total cost = 27(8) +100 = 216 + 100 = 316.
Then, the total cost of 8 skiers is $316.
In a right-triangle, if either of the other two angles are "half that measure", or half of 90°, that means 45°, then the last angle will also have to be a 45° one too, and the sides coming from the 90° angle, will be equal twins, and therefore they can only make up one type-length hypotenuse, and due to that, you can only make that one triangle. Check picture below.
