The required equation of the line is y = -1/2x

<h3>Equation of a line</h3>

The standard equation of a line is expressed as y = mx + b

  • where:
  • m is the slope
  • b is the y intercept

Given the coordinate points (0,0) and (4, -2)

Slope  = -2/4 = -1/2

The intercept is 0 since the line pass through the origin

Hence the required equation of the line is y = -1/2x
