Hi! Can you help me with these I don't understand. And could you give me the correct answer

0 / 10 points 2 0 / 10 points For the point given in rectangular coordinates, find equivalent polar coordinates (r, 0): (7, -7) Transform the polar equation to a Cartesian (rectangular) equation: r = 2 cos 0 O ( - 7V2, = ) O x 2 +y2 = 2x O (- 7V2, # ) O x 2 +y2 = -2x O ( 7 V 2, =# ) X O (7V 2, 7) X O x 2 +y2 =x O x 2 +y2 = -x 3 0 / 10 points Transform the Cartesian (rectangular) equation to a polar | 7 0 / 10 points equation: y = -8 State the correct polar coordinate for the graph shown: Or= -8csc0 Or = 8csc0 X Or = -8 sin 0 Or = 8sin 0 (3, 240) (3, 60) X O (-3,-609) (-3, 240) 9 / 10 points State the correct polar coordinate for the graph shown: O (-5, 5X ) O ( 5, ) X O (5, 57 ) O (-5, 7 )
