How far is (-3,-4) from (4,-4)

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

Y2-Y2 / X2-X1

= - 4 - (-4) / 4 - (-3)

=-4+4 / 4+3

= 0 / 7
