Aline segment has an endpoint at (-3, 9), and its midpoint is at (3,3). what is the ordered pair for the other endpoint of the line segment?

Start at (-3,9).  The increase in x from this point to the midpoint (3,3) is 6.  Add 6 to the x-coordinate of (3,3), obtaining 9, which is the x-coordinate of the other endpoint of the line segment.

Next, notice that y decreases by 6 from 9 to 3 as we travel from (-3,9) to (3,3).   Decrease y again by 6:  3 less 6 is -3.  So the y-coordinate of the other endpoint is -3.  

Thus, the coordinates of the other endpoint are (9, -3).

Let's check whether this is correct or not.  According to the midpoint formula, e find the x-coordinate of the midpoint by summing up the endpoint x values and dividing this sum by 2:  (-3+9)/2 = 3.  This agrees with the given midpoint (3,3).

this doesn't make sense lol

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
