The graph of 2x – 4y > 6 is in the far-right graphic image.
Further explanation
Let us first arrange the equation of the line followed by making a graph of a linear inequality.
Step-1: the x-intercept and the y-intercept
2x - 4y = 6
- For y = 0, we get the x-intercept.
2x - 4(0) = 6
2x = 6, and then divide by two on both sides.
Hence, the x-intercept is [tex]\boxed{x = 3} \rightarrow \boxed{ \ (3, 0) \ }[/tex]
- For x = 0, we get the y-intercept.
2(0) - 4y = 6
-4y = 6, and then divide by -4 on both sides.
Hence, the y-intercept is [tex]\boxed{y = -1\frac{1}{2}} \rightarrow \boxed{ \ (0, -1\frac{1}{2}) \ }[/tex]
Step-2: graph the inequality
- 2x - 4y = 6 is the boundary line and we draw the line dashed since the equality symbol is " > ".
- Test the point (0, 0), as origin, in 2x - 4y > 6, i.e., [tex]\boxed{2(0) - 4(0) > 6} \rightarrow \boxed{ \ 0 > 6, false \ }[/tex]
- So we shade the region which does not contain the test point.

Notes:
To graph a linear equality in two variables, follow the steps.
- Draw the boundary line using a dashed line if the inequality symbol is " < or > ", or a solid line if the inequality symbol is " ≤ or ≥ ".
- Choose a test point which is not on the boundary line and substitute it into the equality.
- Shade the region which includes the test point if the resulting inequality is true, and shades the region which does not contain the test point if the resulting inequality is false.
