The graph represents the water level of a tank after an inlet pipe is turned on. Water Level of a Tank 10 Water Level (in inches) 2 6 8 10 Time (in minutes) Two students explain the meaning of points (0,0) and (1, 2). • Kelvin says point (O.o) means the tank is empty when the inlet pipe is turned on. Paige says point (1, 2) means the water level of the tank goes up by 2 inches every minute. Who is correct? both Kelvin and Paige neither Kelvin nor Paige only Kelvin only Paige

If we take a plane and use the axis to divide it in four, the first quadrant is the top right and the fourth is the top left. a clockwise rotation of 270 degrees takes a point in the first quadrant which we will call (x,y) takes that point and moves it around the origin so it ends up in the fourth quadrant (y, -x). to picture this put a dot in the first quadrant and use it to draw 3/4 of a circle moving your pencil clockwise.as it turns out, it doesn't matter what quadrant you start in, any point (x,y) when rotated 270 degrees clockwise gives you (y,-x). so we take each of the points given and call the point (x,y) and then we have to find (y, -x). so we take the first number (x), change it's sign (-x) and then put it second. we take the second number (y) and put it first.the image of a(-4,4) is a'(4,4)the image of b(6,2) is b'(2,-6)the image of c (1,1) is (1, -1)the image of d (-5,3) is (3,5)
