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

解析
