Answer:
y = [tex]\frac{1}{3}[/tex] x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (600, 200) and (x₂, y₂ ) = (0, 0) ← 2 points on the line
m = [tex]\frac{0-200}{0-600}[/tex] = [tex]\frac{-200}{-600}[/tex] = [tex]\frac{1}{3}[/tex] , then
y = [tex]\frac{1}{3}[/tex] x ← equation of line
