So, if we use the Pythagorean Theorem, we know that a²+b²=c². The a value would be 7, the x values are 7 units away from each other. The b value would be 8, since the y values are 8 units away from each other. So, 7²+8²=c². 7²=49. 8²=64. 49+64=113. But, we need to find the square root of 113, which is ≈10.63
