Answer:
y = -
x +

Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =

with (x₁, y₁ ) = (- 1, 4 ) and (x₂, y₂ ) = (5, 2 )
m =
=
=
= -
, then
y = -
x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 1, 4 )
4 = -
(- 1) + c =
+ c ( subtract
from both sides )
4 -
= c , that is
c =
-
=

y = -
x +
← equation of line
