To go from store A to store B a person would have to walk south 6 city blocks.
Step-by-step explanation:
Step 1:
Store A is at (-2, 3) and store B is at (-2, -3). The shortest way to go from store A to store B is a straight line drawn from A to B.
So the only direction a person needs to go from store A to store B is south (down).
Step 2:
Now we need to calculate how long they have to walk to get from store A to store B.
To find the distance between two points on a graph, we use
[tex]d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}},[/tex] here (-2, 3) is ([tex]x_{1},y_{1}[/tex]) and (-2, -3) is ([tex]x_{2},y_{2}[/tex]).
[tex]d=\sqrt{\left(-2-(-2))^{2}+\left(-3-3)^{2}}[/tex][tex]=\sqrt{0+36} = 6.[/tex]
So a person would have to walk south store A for 6 city blocks to get to store B.
