Choose the linear inequality that describes the graph. The gray area represents the shaded region.


y ≤ 2x – 2

y ≥ 2x – 2

y ≥ 2x + 2

y ≥ –2x + 2

Choose the linear inequality that describes the graph The gray area represents the shaded region y 2x 2 y 2x 2 y 2x 2 y 2x 2 class=

Respuesta :

The given line has the equation y = 2x - 2, so if the gray area is the one of interest, the inequality is y ≥ 2x – 2.

Answer:

The correct option is 2.

Step-by-step explanation:

From the given graph it is noticed that the related line passing through the points (0,-2) and (1,0).

If a line passing through two points, then the equation of line is

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

The related equation is

[tex]y-(-2)=\frac{0-(-2)}{1-0}(x-0)[/tex]

[tex]y+2=2x[/tex]

[tex]y=2x-2[/tex]

So, the related equation is [tex]y=2x-2[/tex].

From the graph it is noticed that the point (0,0) contained in the shaded region.

check the related equation by (0,0).

[tex](0)=2(0)-2[/tex]

[tex]0=-2[/tex]

This statement is true if the sign is [tex]\geq[/tex] insted of equality.

Therefore the required inequality is

[tex]y\geq 2x-2[/tex]

Option 2 is correct.
