Miscellaneous
200
Graph the following system:
200
Write the system of inequalities for the following graph:
200
Is the point (2, 3) a solution to the system?
No, The point lies on the DASHED line, so you cannot include it in the solution!
200
Write the and inequality in slope intercept form.
-x + 3y < 9
y< 1/3x +3
400
Graph the following system:
400
Write a system of inequalities for the following graph:
400
Is the point (25, -5) a solution to the system?
Yes, This point lies in the shaded region.
(Hint: The tick marks on the graph go up by 5's!)
400
If the line is solid and shaded above, which inequality sign will we use?
GREATER THAN OR EQUAL TO
600
Graph the following system:
600
Write a system of inequalities for the following graph:
600
Is the point (2, 6) a solution to the system?
Yes, This point lies on the SOLID line, so it IS a part of the solution!
(Hint: Each tick mark on the graph goes up by 2s!)
600
Graph the system of inequalities, What type of solution is this?
NO SOLUTION

Write a system of inequalities for the following graph:
800
Is (0,0) a solution to the system of inequalities below?
No! The point (0,0) lies outside of the shaded region.
800
Where can we find ordered pairs that are solutions to a system of inequalities?
In the shaded region where the colors overlap
On the solid line of a system of equations
1000
What inequality symbol would you use for the words "no more than?"
1000
Graph the following system:
y >= - 2/3 x + 2
y < 2x - 3
1000
Write a system of inequalities for the following graph:
1000
Answer: D
(Hint: Plug in "x" and "y" for each point to
see which ordered pair makes the inequalities true statements!)
