the easiest way to do this would be to draw yourself a little diagram. If drawing it on the axis you should find that it makes a triangle.

you can then use pythagorus’s theorum to find the distance “as the crow flies” along the hypotenuse of the triange between the two points.

the length of the sides are given to you. the distance between -6 and 8 is 14 and the difference between -2 and 2 is 4.

to work out distance use the formular a^2 + b^2= c^2

so 14 x14= 196 and 4 x 4=16

196 + 16= 212

the distance is = the sqare root of 212 which is approximately 14.56.

simply add on the units later.

hope this helped =)

S. B.

D = â[(x2 – x1)Â² + (y2 – y1)Â²]

D = â[(-6 – 8)Â² + (-2 – 2)Â²]

D = â[(-14)Â² + (-4)Â²]

D = â(196 + 16)

D = â212

D = â(4*53) = 2â53 ~ 14.56

there isn’t much more info?
