Answer:

y = -
(4)/(3) x

Explanation:

the equation of a line passing through the origin is

y = mx ( m is the slope )

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 4) ← 2 points on the line

substitute these values into the formula for m

m =
(4-0)/(-3-0) =
(4)/(-3) = -
(4)/(3)

y = -
(4)/(3) x ← equation of line
