Answer:
Part 2) the answer is the option A) 
Part 3) the answer is the option C) I quadrant
Part 4) the answer is the option D 
Part 5) the graph in the attached figure
Step-by-step explanation:
<u>Part 2)</u> we have

Find the x-intercept
the equation of the line is

The x-intercept is the value of x when the value of y is equal to zero
For 
substitute in the equation of the line


<u>Part 3)</u> If x>=0 and y>=0, then which quadrant holds the solution?
we know that
------> the solution is in the I and IV quadrant
------> the solution is in the I and II quadrant
The solution of the compound inequality is the common quadrant
so
The solution is in the I quadrant
<u>Part 4) </u> Which ordered pair is a solution of the inequality?

we know that
If a ordered pair is a solution of the inequality. then the ordered pair must be satisfy the inequality
Substitute the value of x and y of the point
in the inequality

------> is true
therefore
the point
is a solution of the inequality
<u>Part 5)</u> we have

we know that
The solution is the shaded area above the dashed line
The equation of the line is 
The slope of the line is negative
The y-intercept is the point 
The x-intercept is the point
