Determine whether the situation involves a permutation or a combination, and how many possibilities are there are?
1 answer:
Answer:
This situation involves a combination as the team will be the same no matter what order the students are chosen in.
There are 1402410240 possibilities for the six student team
Step-by-step explanation:
Each time a student is chosen, they cannot be chosen again, so the number of available students decreases each time that one is chosen.

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = B(- 4, 2) and (x₂, y₂ ) = C(- 2, - 2)
m = =
= - 2
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, - 2), then
- 2 = 4 + c ⇒ c = - 2 - 4 = - 6
y = - 2x - 6 ← equation of line through B and C
