Answer:
y = - x -
Step-by-step 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, - 5) and (x₂, y₂ ) = (3, - 6)
m = = -
, then
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, - 5 ) , then
- 5 = - + c ⇒ c = - 5 +
= -
y = - x -
← equation of line
