Answer:

The system of inequalities shown in the graph is x ≤ 4 and y > 1C

Explanation:

  • The equation of a vertical line is x = a, where a is the x-coordinate of any point on the line
  • The equation of a horizontal line is y = b, where b is the y-coordinate of any point on the line

In the given figure, there are 2 lines, let us find the equations of them, then write the inequalities which represent the shaded areas

∵ The purple line is a vertical line

∵ It is cross the x-axis at the point (4, 0)

→ By using the first rule above

∴ The equation of the purple line is x = 4

∵ The purple line is solid and the shaded area left the line

∴ The sign inequality is ≤

The inequality of the purple area is x ≤ 4

∵ The blue line is a horizontal line

∵ It is cross the y-axis at the point (0, 1)

→ By using the second rule above

∴ The equation of the blue line is y = 1

∵ The blue line is dashed and the shaded area above the line

∴ The sign inequality is >

The inequality of the blue area is y > 1

The system of inequalities shown in the graph is x ≤ 4 and y > 1
