Question

Find the coordinates of the four points which have integer coordinates and are a distance of root 5 from the point (1, 2). Hint 5=1^2 + 2^2

Answer 1

so, move left-right 1 and up-down 2

or left-right 2 and up-down 1.

One such point will be (1+1,2+2) = (2,4)

I think you will find 8 such points, not 4.

Answer 2

Step1: Mark the point (1,2) on a Cartesian plane.
Step2: Go 2 units up and 1 unit right that will be your point A (2,4)
Step3: Go 2 units up and 1 unit left that will be your point B (0,4)
Step4: Go 2 units down and 1 unit right that will be your point C (2,0)
Step5: Go 2 units down and 1 unit left that will be your point D (0,0)

Answer 3

These are your four points
A: (2,4)
B: (0,4)
C: (2,0)
D: (0,0)
Hope this helps

Answer 4

please hwo does this work i need the woring out to understnad

Answer 5

hey maybe if you think about it like sqrt= square root
\sqrt{5}=\sqrt{1^2+2^2}
move one left or right
move 2 up or down

Answer 6

hey
