What else can I help you with?
Are these ordered pairs in direct variation 1 1 3 3 5 5?
yes
What are the ordered pairs of x4y and 3x-2y20?
there are none, ordered pairs come from equations like x = 2y -5
A set of ordered pairs?
Coordinates
What is a rule for the function identified by this set of ordered pairs?
You didn't show the Ordered Pairs so there is no way this question could be answered.
Which ordered pairs satisfy the equation y equals -9x?
There are infinitely many ordered pairs. One of these is (0, 0).
Is 20 a direct variation?
No. It is a single number. For a direct variation you need a minimum of two pairs of ordered numbers.
Are these ordered pairs in direct variation 1 1 3 3 5 5?
yes
Are these ordered pairs in direct variation -1 0 3 2 9 6?
No. For direct variation, any order pair with a 0 in it MUST be (0,0).
What are the ordered pairs for 20?
The Ordered Pairs are 1x20, 2x10, and 5x4.
What is -1 in ordered pairs?
-1 is a one-dimensional entity. It can have no equivalent in ordered pairs.
How do you find y in a set of ordered pairs?
Y is the second number in a set of ordered pairs.
Which ordered pairs are in the second quadrant?
Ordered pairs that have a negative x and a positive y are in the second quadrant.
Ordered pairs are used to?
Ordered pairs are used for many things. Anytime you graph a point on a cartesian coordinate system, you have an ordered pair. In fact, all of R^2 is made up of ordered pairs. When you put a value in a function and get one out, you have an ordered pair
When two quantities form a direct variation what is it called?
A direct variation (!) or direct reelationship.
Is direct variation a special case?
Direct variation is not a special case.
Is y equals 3x direct variation?
Yes, it is direct variation.
Is y equals 2x plus 5 a direct variation if so what is the constant of variation?
No, it is not a direct variation.
