Answer:
y = 2x
Step-by-step 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 = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
let (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, - 6) ← 2 points on the line
substitute these values into the formula for m
m = [tex]\frac{-6-0}{-3-0}[/tex] = [tex]\frac{-6}{-3}[/tex] = 2
y = 2x ← equation of line
