Question

Calculate the distance between the two points (7,0) and (2,-12)​

Answer 1

Answer:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

(x2-x1) = (2 - 7) = -5

(y2-y1) = (-12 - 0) = -12

Square the results and sum them up:

(-5)2 + (-12)2 = 25 + 144 = 169

Now Find the square root and that's your result:

Exact solution: √169 = 13

Approximate solution: 13
