Answer:
Direct Variation. Since k is constant we can find k when given any point by dividing the y-coordinate by the x-coordinate.
Answer:
C. (-2,2π/3)
Step-by-step explanation:
Given:
In the given plane, each line represents angles and the circles shows the radii. Now as full circle is of 360 degrees or 2π and there are 12 straight lines that means
every angle is π/6 apart (30 degrees).
As the given red point is on circle 2, this means the radii, r=2
and Ф=300 degrees or 5π/3
r=(2,5π/3)
but above is not given in the options.
Polar coordinates can have positive or negative theta and also have positive or negative radii. In case of negative radii the polar coordinate moves in opposite direction of the pole.
if we consider r=-2 then we have to move in opposite direction of pole of Ф=300 degrees or 5π/3 is 120 degrees or 2π/3.
hence r=-2 andФ=2π/3
Correct option is C:(-2,2π/3)!
