Answer:
y - 6 = -
(x + 1)
Explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
calculate m using the slope formula
m =

with (x₁, y₁ ) = (- 1, 6 ) and (x₂, y₂ ) = (1, 5 )
m =
=
= -

using (a, b ) = (- 1, 6 ) , then
y - 6 = -
(x - (- 1) ) , that is
y - 6 = -
(x + 1) ← equation of line in point- slope form
