we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
in this problem we have
the point is on the line of direct variation
so
Find the constant of proportionality k
-------> substitute ------>
the equation is
Remember that
If a point is on the line of direct variation
then
the point must satisfy the equation of direct variation
we're proceeding to verify each point
<u>case A)</u> point
Substitute the value of x and y in the direct variation equation
-------> is true
therefore
the point is on the line of direct variation
<u>case B)</u> point
Substitute the value of x and y in the direct variation equation
-------> is true
therefore
the point is on the line of direct variation
<u>case C)</u> point
Substitute the value of x and y in the direct variation equation
-------> is not true
therefore
the point is not on the line of direct variation
<u>case D)</u> point
Substitute the value of x and y in the direct variation equation
-------> is true
therefore
the point is on the line of direct variation
<u>case E)</u> point
Substitute the value of x and y in the direct variation equation
-------> is not true
therefore
the point is not on the line of direct variation
<u>case F)</u> point
Substitute the value of x and y in the direct variation equation
-------> is true
therefore
the point is on the line of direct variation
therefore
<u>the answer is</u>
Answer:
See diagram
Step-by-step explanation:
First, consider the graph of the parent function This function has the period
Rewrite the function as
The graph of this function has the same period of
is twice streched and translated
units to the right and 2 units up graph of the parent function (see diagram).
