Test Your Knowledge: Algebra!

It's a known fact that very few people are particularly fond of mathematics. Or at least, they're totally fine until the alphabet decides to step in out of nowhere.

But some people are. And if you are, then this quiz was practically made for you. If not...well, good luck! It shouldn't be too hard if you know what you're doing. And last but not least, be sure to READ THE QUESTIONS CAREFULLY. Getting a question wrong because you didn't read it correctly is painful!

Let's start with an easy one...What is the value of x in the equation x+7=9?
- 16
- 2
- 79
- -2
What is the solution to 5x-9≥6?
- x ≥ -1
- x ≥ 3
- x ≤ 3
- x ≥ -3
What letter represents the y-intercept in the point slope form equation?
- y
- m
- x
- b
What is the absolute value of -9?
- -9
- 9
- -3^2
- √63
5x+2y=6 and -5x-2y=2. What is a possible solution to the system?
- x=0 and y=3
- x=2 and y=1
- x=0 and y=0
- There is no solution.
An "Identity" is an equation where...?
- There are two or more solutions.
- There is no solution.
- There is only one solution.
- There is an infinite number of solutions.
If I were to write a dot to represent x ≥ 2 on a graph, would the dot be open or closed?
- Open, because the valid numbers are greater than zero.
- Closed, because the arrow would point to the right.
- Closed, because 2 is included in the solution.
- Open, because it is an even number.
In the equation y= (x-2) + 9, the line on the graph would be moved in what two directions?
- 2 units down, 9 units right
- 2 units up, 9 units down
- 2 units right, 9 units up
- 2 units left, 9 units up
Which of the following is NOT undefined?
- The square root of -9
- 6 divided by 0
- A horizontal line on a graph
- A vertical line on a graph
In the equation 2y +9x > -2, what type of line would you draw, and what part would you shade?
- A solid line with the above area shaded
- A dotted line with the below area shaded
- A dotted line with the above area shaded
- A solid line with the below area shaded
9x -2y > 0; is (-4,5) a solution?
- Yes
- No
- Not enough information
Is a graph with several lines that are not connected considered discreet, continuous, or neither?
- Discreet
- Continuous
- Neither
Is a linear, diagonal line on a graph considered one-to-one or onto, assuming the codomain is all real numbers?
- One-to-one
- Onto
- Both
- Neither
Which of the following would NOT be considered one-to-one or onto if it were to be placed on a graph? (Again, assuming the codomain is all real numbers)
- The trajectory of a ball thrown into the air
- A living person's heartbeat
- A professional diver jumping off of a diving board
- All of the above
- None of the above
Which of the following would have a slope of zero if it were to be placed on a graph?
- A person skydiving from a plane
- A living person's heartbeat
- A deceased person's heartbeat
- A basketball being pushed underwater
True or false: Vertical lines on a graph are undefined because the slope is zero divided by a number.
- True
- False
True or false: Negative numbers have no square roots because a negative multiplied by a negative gives you a positive.
- True
- False
True or false: A graph which only has a bunch of random dots is always discreet.
- True
- False
"If you can sketch a graph without raising your pencil off of it, it is continuous." Is this a true statement?
- Yes
- No
"In the equation 5x - 2 > 12, you must flip the sign because you are dividing to get the solution." Is this a true statement?
- Yes
- No
