Determine whether y varies directly with x. If so, find the constant of variation and write the equation.
1 answer:
Answer: B. No
Step-by-step explanation:
Direct variation has the following form:
Where the constant of variation is "k".
By definition, in direct variation, when the variable "x" changes, tha variable "y" changes in proportion to the variable "x".
As you can observe in the table, when the value of the variable "x" increase, the values of the variable "y" decrease, therefore we can conclude that it is not a direct variation.
Then the answer is the option B.

It would look like this
when the sign has a line under it (>) the circle is closed and is a solid line. when there is no line under > its open and dotted.its -3 so you put the dot on -3. if x is greater than(in which this case it is)fill in the line greater than -3.
hope this helped!!
