Answer:
y + 1 = - (x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - y₁ = m(x - x₁)
where m is the slope and (x₁, y₁) a point on the line
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 4, - 1) and (x₂, y₂ ) = (3, - 3)
m = =
= -
and (x₁, y₁ ) = (- 4, - 1), then
y - (- 1) = - ( x - (- 4) ) , that is
y + 1 = - (x + 4) ← equation of line
Answer:
base = e
Step-by-step explanation:
The general log function is defined as
.... (1)
where, a is the base of the log function.
The natural logarithm function is
It can be rewritten as
.... (2)
where, e is a constant or Euler's number is:
e ≈ 2.71828183
On comparing (1) and (2) we get
Therefore, the base of the natural logarithm function is e.
