Q. Find the distance between the points (3,7) and (9,7).____ units
Calculate x-coordinate difference: Calculate the difference in x-coordinates between the two points (3,7) and (9,7).Difference in x-coordinates = 9−3=6
Calculate y-coordinate difference: Since the y-coordinates are the same 7 and 7, the difference in y-coordinates is 0.Difference in y-coordinates = 7−7=0
Use distance formula: Use the distance formula: Distance = (difference in x)2+(difference in y)2.Distance = (6)2+(0)2=36+0=36=6 units
