Answer:
c = 
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 
m = 
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (2, c)
m =
=
, then
=
( cross- multiply )
2(c - 4) = - 3
2c - 8 = - 3 ( add 8 to both sides )
2c = 5 ( divide both sides by 2 )
c = 
Answer:
8P5=8! (8−5)! =8×7×6×5×4×3!
