we need to find the equations of the lines that separates the plane. The red line has a y-intercept -4 and for every 2 units to the right it decreases 1 unit, then the slope is -1/2. So, the equation of the red line is
The dashed line passes through the origin, so the y-intercept is 0, also, for every 1 unit to the right it increases 2 units, then the slope is 2 and the equation is
Finally, we see that the red region is below the the red line and it includes de red line, and the blue region is above the blue line and it doues not include the line, so the inequalities are
multiplying the first inequality by 2
Then, the correct answer is the first one
