Question

Find the distance between the points (–2, –6) and (0, 5)

Answer 1

We use the formula $\sqrt{(5 + 6)^{2} + (0 + 2)^{2}} = \sqrt{121 + 4} = \sqrt{125}$≈ 11.18;

Answer 2

$\sqrt{(x2 - x1) ^{2} + (y2 - y1) ^{2} }$
x2=0
x1=-2
y2=5
y1=-6

$\sqrt{(0 - (- 2)) ^{2} + (5- ( - 6) ^{2} }$
$\sqrt{(0 + 2) ^{2} + (5 + 6) ^{2} }$
$\sqrt{(2) ^{2} + (11) ^{2} }$
$\sqrt{(4) + (121) }$
$\sqrt{125}$
