Question

Please help me write two questions in Rectangular and Polar Forms.

Write is Polar form
-2x-6y=7

Write is Rectangular Form
r=-12costheta

Answer 1

Your rectangular coordinate doesn't make sense to me, but I can help with the polar one.

Answer 2

Please help, I don't understand how to rewrite it.

Answer 3

To convert polar to rectangular, we use trigonometry!
X: r*cos(theta) =
Y: r*sin(theta) =

Answer 4

Yeah, but how do I use those? Which numbers do I use?

Answer 5

Look at your polar coordinate.
r = 12, the distance from the origin. Theta is the angle from the x-axis. I'll draw it.
