Let's find the distance between two points. 8 7 units apart 7 (-6,4) 6 5 4 3 2 1 (1,4) So the distance from (-6,4) to (1,4) is 7. -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 -2 -3 -4 -5 -6 -7 If the points are located horizontally from each other, the y coordinates will be the same. You can look to see how far apart the x coordinates are. What coordinate will be the same if the points are located vertically from each other? (-6,4) 7 units apart 8 7 6 5 4 3 2 1 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 -2 -3 -4 -5 -6 -7 (-6,-3) So the distance from (-6,4) to (-6,-3) is 7. If the points are located vertically from each other, the x coordinates will be the same. You can look to see how far apart the y coordinates are. Let's use it to find the distance between (3, -5) and (-1,4) Plug these values in the distance formula c c 4 9 2 2 CAUTION! x-12 (x1,y1) x31 2 y42 (x2,y2) -5 y1 16 81 2 means approximately equal to 97 9.8 found with a calculator Don't forget the order of operations! You must do the brackets first then powers (square the numbers) and then add together BEFORE you can square root
