Question

you start at (7,6) you move left 1 unit 3 units. where do you end

Answer 1

Let,

$(x,y)=(7,6)$

Moving one unit to the left means substracing one unit from the x coordinate.

$\begin{gathered} (x-1,y)=(7-1,6) \\ (6,6) \end{gathered}$

If we move one unit to the left we end up at (6,6).

Moving 3 unit to the left from (7,6).
