Example Questions

Example Question #1 : Graphing An Ordered Pair

Which of the following ordered pairs is in Quadrant III?

Possible Answers:

Correct answer:

Explanation:

By definition, only Quadrant III contains ordered pairs that have both negative - and -coordinates. 

Example Question #21 : How To Graph An Ordered Pair

Which quadrant or axis includes the point ?

Possible Answers:

Quadrant III

Quadrant II

The -axis

Quadrant I

Quadrant IV

Correct answer:

Quadrant II

Explanation:

The ordered pair  has a negative -coordinate and a positive -coordinate. By definition, all ordered pairs with negative -coordinates and a positive -coordinates exist in Quadrant II.

Example Question #6 : Graphing An Ordered Pair

Which quadrant or axis includes the point ?

Possible Answers:

The -axis

Quadrant III

The -axis

Quadrant II

Quadrant I

Correct answer:

The -axis

Explanation:

The ordered pair  has a zero -coordinate and a nonzero -coordinate. By definition, all ordered pairs with zero -coordinates and nonzero -coordinates is on the -axis.

Example Question #101 : Graphing

Which of the following ordered pairs is in Quadrant I?

Possible Answers:

None of these coordinates

Correct answer:

Explanation:

 By definition, all ordered pairs with positive -coordinates and positive -coordinates are in Quadrant I. Therefore, the only ordered pair in this quadrant is .

Example Question #1 : Graphing A Point

The point  lies on a line with slope  that passes through the point

What is ?

Possible Answers:

cannot be determined

Correct answer:

Explanation:

We first need to find an equation of the line with a slope of  that passes through the point (2, 5).

Now, plug in the point  and solve for .

Example Question #51 : Graphing

A line goes through points . What is ?

Possible Answers:

Correct answer:

Explanation:

The slope of the line through  and  can be found using the slope formula:

Set :

We can use this slope and the slope formula; set :

Example Question #3 : Graphing A Point

The point  lies on a line with a slope  that passes through . What is the value of ?

Possible Answers:

Correct answer:

Explanation:

In order to find the value of , we first need to find the equation for the line with slope  that passes through the point 

Plugging in  and solving for :

 

Example Question #4 : Graphing A Point

The point  lies on a line with a slope  that passes through . What is the value of ?

Possible Answers:

Correct answer:

Explanation:

In order to find the value of , we first need to find the equation for the line with a slope  that passes through 

 

Plugging in  and solving for :

 

 

Example Question #5 : Graphing A Point

The point  lies on a line with a slope  that passes through . What is the value of ?

Possible Answers:

Correct answer:

Explanation:

In order to find the value of , we first need to find the equation for the line with a slope  that passes through 

Plugging in  and solving for :

Example Question #121 : Graphing

What is the domain of y = 4 - x^{2}?

Possible Answers:

x \geq 4

all real numbers

x \leq 4

x \leq 0

Correct answer:

all real numbers

Explanation:

The domain of the function specifies the values that  can take.  Here, 4-x^{2} is defined for every value of , so the domain is all real numbers.
