Question

you start at (-5, -1). you move down 2 units. where do you end?

Explanation:

Step1: Recall coordinate - movement rule

Moving down changes the y - coordinate. The x - coordinate remains the same when moving vertically.
The starting point is $(-5,-1)$. The x - coordinate of the starting point is $x=-5$.

Step2: Calculate the new y - coordinate

Moving down 2 units means subtracting 2 from the y - coordinate of the starting point. The y - coordinate of the starting point is $y = - 1$. The new y - coordinate is $y=-1 - 2=-3$.
The x - coordinate stays $x=-5$.

Answer:

$(-5,-3)$
