Question

PLEASE CORRECT ME IF IM WRONG WITH GOOD EXPLANATION

I COUNTED THE SQUARES FROM G TO H POINT AND GOT 6 AM I RIGHT ?

Answer 1

6 is the correct answer - good job! There are two ways to do it. The first, and this case the easiest, way is to count the squares just like you did. The other is to use the distance formula:

distance = √[(x₂-x₁)²+(y₂-y₁)²]

You can use either point as (x₁,y₁); you'll get the same answer. I chose point H:

distance = √[(3-3)²+(4-(-2))²] = √(6²) = 6

You'll notice that when the points have the same x-coordinate like points G and H do that the x₂-x₁ term equals zero in the distance formula.

Answer 2

4-(-2) = 4+2 = 6

the difference in y coordinates is the distance, when the x coordinates are the same
