Question

What is the distance from the point (0,-4) to point (4,4)?

Answer 1

Answer: Distance is 8.9

Step-by-step explanation:

$d = √((x2-x1)2 + (y2-y1)2)$

$(x2-x1) = (4 - 0) = 4$

$(y2-y1) = (4 -4) = 8$

Add it all together

$(4)2 + (8)2 = 16 + 64 = 80$

Square 80

$\sqrt{80} =4\sqrt{5} \\=8.9443$

Answer 2

Answer: d=8.9

Step-by-step explanation:

√80=8.9
