Question

you move right 7 units and left 1 unit. you end at (4, -4). where did you start?

Explanation:

Step1: Analyze horizontal movement

Let the starting x - coordinate be $x$. Moving right 7 units and left 1 unit means the net right - ward movement is $7 - 1=6$ units. So $x+6 = 4$.

Step2: Solve for starting x - coordinate

$x=4 - 6=-2$. The y - coordinate doesn't change during horizontal movement, so it starts at $y=-4$.

Answer:

$(-2,-4)$
