Question

Find the distance between points (-4, -6) and (5, -1).

Answer 1

Use the distance formula:

\[D = \sqrt{(x_{2}-x _{1})^{2}+(y_{2}-y_{1})^{2}}\]

Answer 2

plot them on a number plane and use pythagoras' theorem




this gives you the lengths of the right triangle

just use pythagoras to find d

Answer 3

D= 10.3

Answer 4

do a question this way eliminates the need to memorise another formula

Answer 5

that would be very close

Answer 6

yep that's an approximate form the exact is \[\sqrt{106}\]
