问题 Solve for y if the distance between the two points (2,8) and (-6,y) is 17.
选项
答案  Use the Distance Formula to solve this problem. Because you are given the distance between the points, your equation will look like this:
[*]
   Square both sides and solve for Y2:
   289=(-8)2+(y2-8)2
   289=(64)+(y2-8)2
   225=(y2-8)2
    15=y2-8
    23=y2
