A is the correct answer.
Point Slope Form: y - y₁ = m(x - x₁)
m = slope ⇒ -4/7
Coordinate: (-1 , 4)
x₁ y₁
All you have to do is plug in all of the information above into the formula.
y - 4 = -4/7(x +1)

Answer:
A person can select 3 coins from a box containing 6 different coins in 120 different ways.
Step-by-step explanation:
Total choices = n = 6
no. of selections to be made = r = 3
The order of selection of coins matter so we will use permutation here.
Using the formula of Permutation:
nPr =
We can find all possible ways arranging 'r' number of objects from a given 'n' number of choices.
Order of coin is important means that if we select 3 coins in these two orders:
--> nickel - dime - quarter
--> dime - quarter - nickel
They will count as two different cases.
Calculating the no. of ways 3 coins can be selected from 6 coins.
nPr = =
nPr = 120
