For this case, we find the equation of the line of the form:

y = mx + b

Where:

m = \frac {y2-y1} {x2-x1} = \frac {-3-0} {0 - (- 3)} = \frac {-3} {3} = - 1

So, we have:

y = -x + b

We substitute one of the points:0 = - (- 3) + b\\0 = 3 + b\\b = -3

Thus, the equation is:

y = -x-3

Now, we substitute a point belonging to the region to determine the sign.

((0,0)\\0? - (0) -3\\0? -3

-3 is less than 0.

Then, the inequality is:

y> -x-3

As the border of the region is dotted, then it remains ">."

Answer:

y> -x-3

sertanlavr [38]

Answer:

the area of the shape is 7.14

Step-by-step explanation:

First, find the area of the square:

2 in x 2 in = 4 in

then to find the area of the semi- circles add them together to make a circle

To find the area of the circle, use:

pi x radius^2  

Since the diameter is 2 divide the diameter by 2 to get radius  

3.14 x 1^2 = 3.14

The circle is 3.14 plus 4 ( the square ) = 7.14
