How do you convert

(- 2 x, - 2 y)

into polar coordinates?

https://socratic.org/questions/how-do-you-convert-2x-2y-into-polar-coordinates

Gaya3 Oct 14, 2017 For

r

r^{2} = x^{2} + y^{2}

r^{2} = (- 2 x)^{2} + (- 2 y)^{2}

r^{2} = 4 x^{2} + 4 y^{2}

What is the equation of the line perpendicular to

- x + y = 7

and passing through

(- 1, - 1)

https://socratic.org/questions/what-is-the-equation-of-the-line-perpendicular-to-x-y-7-and-passing-through-1-1

The equation of line in point

(- 1, - 1)

slope form is

y + 1 = - (x + 1)

Explanation: The slope of the line

- x + y = 7 or y = x + 7 [y = m_{1} x + c]

Different methods for finding the minimum of

∣ x - 2 y ∣

when

x^{2} + 1 = 2 y^{2}

https://math.stackexchange.com/questions/1794192/different-methods-for-finding-the-minimum-of-x-2y-when-x21-2y2

Calculations give us

(x - 2 y)^{2} = 2 (x - y)^{2} + 1 \geq 1

Thus we have

∣ x - 2 y ∣ \geq 1

With the equality holding when

x = y = \pm 1

Equation of pair of straight lines perpendicular to another pair of lines

https://math.stackexchange.com/questions/2592709/equation-of-pair-of-straight-lines-perpendicular-to-another-pair-of-lines

Note that the equation of the lines represented by the equation

4 x y + 2 x + 6 y + 3 = 0

are given by

2 x + 3 = 0

and

2 y + 1 = 0

. Therefore you can find the equation of the lines perpendicular to these two ...

Confused regarding the answer of a problem based on locus.
