Answer:
y = x - 11
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 ) = (4, - 5 ) and (x₂, y₂ ) = (8, 1 )
m = =
=
=
, then
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 1 ) , then
1 = 12 + c ⇒ c = 1 - 12 = - 11
y = x - 11 ← equation of line in slope- intercept form
