X= y
u have to divide 7 from both sides
Answer:
what are the available options then I can answer
Find the polar coordinates in the usual way, then negate r and add 180° to θ.
You know that
... r = √(x² + y²)
... θ = arctan(y/x) . . . . . taking quadrant into account
The coordinates (r, θ) and (-r, θ+180°) specify the same point.
