Q. Find the distance between the points (8,7)(8,7) and (8,3)(8,3).\newline____ units
  1. Apply distance formula: Step 11: Apply the distance formula (x2−x1)2+(y2−y1)2\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}.\newlineGiven points (x1,y1)=(8,7)(x_1, y_1) = (8, 7) and (x2,y2)=(8,3)(x_2, y_2) = (8, 3).\newlineCalculate (x2−x1)2(x_2-x_1)^2: (8−8)2=02=0(8-8)^2 = 0^2 = 0
  2. Calculate squares: Step 22: Calculate (y2−y1)2(y_2-y_1)^2: (3−7)2=(−4)2=16(3-7)^2 = (-4)^2 = 16
  3. Compute square root: Step 33: Compute the square root of the sum of squares: 0+16=16=4\sqrt{0 + 16} = \sqrt{16} = 4
