(3, -5)
(-6, 5)
(5, 8)
(-3, 6)
Word 2:
(6, 5)
(-6, 5)

Mission 2: Quadrant Sorting Vault
Classify each of the 26 plotted letters by recording them in their correct quadrant or axis location:
Quadrant I (+, +) • 6 Letters
Quadrant II (-, +) • 6 Letters
Quadrant III (-, -) • 5 Letters
Quadrant IV (+, -) • 6 Letters
On an Axis x=0 or y=0 • 3 Letters
Mission 3: Coordinate Geometry & Distance
1. Horizontal Segment \(\overline{AM}\) A(-6, 5) & M(6, 5)
Both have \(y=5\). What is the horizontal distance?
Distance:
units
2. Vertical Segment \(\overline{DT}\) D(0, 6) & T(0, -4)
Both lie on the y-axis (\(x=0\)). What is the vertical distance?
Distance:
units
3. Midpoint Discovery
Midpoint halfway between \(A(-6, 5)\) and \(M(6, 5)\):
Midpoint: (

Mission 4: Reflection & Symmetry Challenge
1. Reflect \(K(4, 2)\) across x-axis:

3. Reflect \(Z(-1, -1)\) through origin:
(
,
)
Rule: In reflection across x-axis, the -value changes; across y-axis, the -value changes.
