Answer:

y = -
(1)/(2) x

Explanation:

the equation of a line passing through the origin is

y = mx ( m is the slope of the line )

calculate m using the slope formula

m =
(y_(2)-y_(1) )/(x_(2)-x_(1) )

with (x₁, y₁ ) = (- 8, 4) and (x₂, y₂ ) = (0, 0) ← 2 points on the line

m =
(0-4)/(0-(-8)) =
(-4)/(0+8) =
(-4)/(8) = -
(1)/(2) , then

y = -
(1)/(2) x ← equation of line
