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
