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
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
Substitute the value of x and y in the direct variation equation
therefore
the point is on the line of direct variation
Substitute the value of x and y in the direct variation equation
therefore
the point is on the line of direct variation
Substitute the value of x and y in the direct variation equation
therefore
the point is not on the line of direct variation
Substitute the value of x and y in the direct variation equation
therefore
the point is on the line of direct variation
Substitute the value of x and y in the direct variation equation
therefore
the point is not on the line of direct variation
Substitute the value of x and y in the direct variation equation
therefore
the point is on the line of direct variation
therefore
the answer is
