Part A: The graph of given inequality is shown below.

Part B: The point (4,6) is not a solution of given system of inequalities.

Step-by-step explanation:

Part A:

The given inequalities are

y2x+3

The related equation of given inequalities are

y=2x+3

$y=-\frac{3}{2}x-4$

Put x=0, to find the y-intercepts.

y=2(0)+3=3

$y=-\frac{3}{2}(0)-4=-4$

Put y=0, to find the x-intercepts.

$0=2x+3\Rightarrow x=-\frac{3}{2}$

$0=-\frac{3}{2}x-4\Rightarrow x=-\frac{8}{3}$

The x and y-intercepts of first line are (0,3) and (-1.5,0) respectively. The x and y-intercepts of second line are (0,-4) and (-2.667,0) respectively.

Check the given inequality by (0,0).

02(0)+3

This statement is false. It means (0,0) is not the solution of this inequality and the shaded region is opposite side of the origin.

The graph of given inequalities is shown below.

Part B:

We have to check whether (4,6) is a solution of the system of inequality or not.

Check the given inequality for the point (4,6).

(6)2(4)+3

611

This statement is false. It means (4,6) is not the solution of given system of inequalities.

Answer from: Gabriel134

We are given the system of inequalities,

y2x+3 and

Part A: We have that the equations given are straight line which have the intersection point (-2,-1).

According to 'Zero Test' which states that 'After substituting (0,0) in the inequalities. If the result is true, the solution region is towards the origin. If the result is false, the solution region is away from the origin'.

So, from the graph we see that the solution region is away from the origin, which means both the given inequalities fails the 'Zero Test'.

i.e. y2x+3 ⇒ 0 > 3, which is false and ⇒ 0 < -4, which is also false.

Part B: We see that from the graph, that the point (4,6) lies outside the solution region.

Mathematically, we will substitute the value of x= 4 in the equality to check whether the value of y= 6.

So, y=2x+3 ⇒ $y=2\times 4+3$ ⇒ y=8+3 ⇒ y= 11

And, $y=-\frac{3}{2}x-4$ ⇒ ⇒ $y=-3\times 2-4$ ⇒ y=-6-4 ⇒ y= -10.

Hence, we see that mathematically the point (4,6) does not lie in the solution region.
