Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)
m = =
= -
------------------------------------------
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y = 5 - 2x , that is
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2
