Question

akila walks 2 units to the right and 3 units up from her locker to get to the school library. she ends up at the point (5, 4) on the coordinate plane. where was her locker located initially?

Explanation:

Step1: Reverse the right - ward movement

To reverse the 2 - unit right - ward movement, we subtract 2 from the x - coordinate of the final point. The x - coordinate of the final point is 5. So, $x=5 - 2$.
$x = 3$

Step2: Reverse the upward movement

To reverse the 3 - unit upward movement, we subtract 3 from the y - coordinate of the final point. The y - coordinate of the final point is 4. So, $y=4 - 3$.
$y = 1$

Answer:

$(3,1)$
