  1. Distance Formula Application: To determine which options are 44 units away from point JJ, we need to consider the distance formula in a 2D2D coordinate system, which is d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}, where (x1,y1)(x_1, y_1) is the original point and (x2,y2)(x_2, y_2) is the point we're measuring the distance to. We will apply this formula to each option to see if the distance is 44 units.
  2. Option A Calculation: For option A (x-axis), we need to find a point on the x-axis that is 44 units away from JJ. Since JJ is at (4,4)(-4,4), a point on the x-axis that is 44 units away would have to be at (4,0)(-4,0) because the yy-coordinate would be 00 (on the x-axis) and 44 units away in the yy-direction. Let's calculate the distance:\newlined=(4(4))2+(04)2d = \sqrt{(-4 - (-4))^2 + (0 - 4)^2}\newlined=(0)2+(4)2d = \sqrt{(0)^2 + (-4)^2}\newlined=0+16d = \sqrt{0 + 16}\newlined=16d = \sqrt{16}\newlined=4d = 4\newlineThe x-axis is indeed 44 units away from point JJ at the specific point (4,0)(-4,0).
  3. Option B Calculation: For option B (4,8)(-4,8), we will use the distance formula to find the distance from JJ to this point:\newlined=(4(4))2+(84)2d = \sqrt{(-4 - (-4))^2 + (8 - 4)^2}\newlined=(0)2+(4)2d = \sqrt{(0)^2 + (4)^2}\newlined=0+16d = \sqrt{0 + 16}\newlined=16d = \sqrt{16}\newlined=4d = 4\newlineThe point (4,8)(-4,8) is also 44 units away from point JJ.
  4. Option C Calculation: For option C (y-axis), we need to find a point on the y-axis that is 44 units away from JJ. Since JJ is at (4,4)(-4,4), a point on the y-axis that is 44 units away would have to be at (0,4)(0,4) because the xx-coordinate would be 00 (on the y-axis) and it would not be 44 units away in either direction since the yy-coordinate is the same as JJ's. Therefore, the y-axis is not 44 units away from point JJ at any specific point.
