### Problem 5:
# Explanation:
## Step1: Identify translation rule
The translation rule is $(x, y) \to (x + 1, y - 3)$. For point $Q(5, 9)$, we substitute $x = 5$ and $y = 9$ into the rule.
## Step2: Calculate new coordinates
For the $x$-coordinate: $5 + 1 = 6$. For the $y$-coordinate: $9 - 3 = 6$. So the image of $Q$ is $(6, 6)$.
# Answer:
$(6, 6)$

### Problem 6:
# Explanation:
## Step1: Use translation rule
The rule is $(x, y) \to (x + 1, y - 3)$. For $M(-3, -8)$, substitute $x = -3$ and $y = -8$.
## Step2: Compute new points
$x$-coordinate: $-3 + 1 = -2$. $y$-coordinate: $-8 - 3 = -11$. Thus, the image is $(-2, -11)$.
# Answer:
$(-2, -11)$

### Problem 7:
# Explanation:
## Step1: Translate each vertex
For $C(-1, 3)$: $x = -1 - 3 = -4$, $y = 3 + 1 = 4$ → $C'(-4, 4)$.
For $D(0, -2)$: $x = 0 - 3 = -3$, $y = -2 + 1 = -1$ → $D'(-3, -1)$.
For $E(1, 1)$: $x = 1 - 3 = -2$, $y = 1 + 1 = 2$ → $E'(-2, 2)$.
## Step2: Graph the triangle
Plot $C, D, E$ and $C', D', E'$ on a coordinate plane and connect the vertices.
# Answer:
Vertices of image: $C'(-4, 4)$, $D'(-3, -1)$, $E'(-2, 2)$ (graphing involves plotting these points).

### Problem 8:
# Explanation:
## Step1: First translation
Apply $(x, y) \to (x + 10, y - 8)$ to each vertex:
- $C(-1, 3)$: $x = -1 + 10 = 9$, $y = 3 - 8 = -5$ → $C_1(9, -5)$.
- $D(0, -2)$: $x = 0 + 10 = 10$, $y = -2 - 8 = -10$ → $D_1(10, -10)$.
- $E(1, 1)$: $x = 1 + 10 = 11$, $y = 1 - 8 = -7$ → $E_1(11, -7)$.
## Step2: Second translation
Apply $(x, y) \to (x - 7, y + 15)$ to $C_1, D_1, E_1$:
- $C_1(9, -5)$: $x = 9 - 7 = 2$, $y = -5 + 15 = 10$ → $C'(2, 10)$.
- $D_1(10, -10)$: $x = 10 - 7 = 3$, $y = -10 + 15 = 5$ → $D'(3, 5)$.
- $E_1(11, -7)$: $x = 11 - 7 = 4$, $y = -7 + 15 = 8$ → $E'(4, 8)$.
## Step3: Graph the triangle
Plot original and final image vertices and connect.
# Answer:
Final image vertices: $C'(2, 10)$, $D'(3, 5)$, $E'(4, 8)$ (graphing requires plotting these).

### Problem 9:
# Explanation:
## Step1: Analyze collinearity
Collinear points lie on the same line, but we only know three points are collinear ($A$, $A'$, $A''$) with $A(-2, 3)$ and $A''(3, 7)$. There are infinitely many points $A'$ on the line through $A$ and $A''$ unless more constraints (like $A'$ being a midpoint, specific ratio, etc.) are given.
## Step2: Conclusion
We don't have enough info to find unique $x$ and $y$ for $A'$ because collinearity alone doesn't fix a single point between $A$ and $A''$ (or beyond) without additional details (e.g., $A'$ is the midpoint, or a specific translation/ratio).
# Answer:
No, we do not have enough information. Collinearity means $A'$ lies on the line through $A$ and $A''$, but there are infinitely many such points without more constraints (e.g., midpoint, specific translation, etc.).

### Problem 10:
# Explanation:
## Step1: Determine translation
From Community Center (let's assume its coordinates, e.g., if Community Center is at $(2, 4)$ and Post Office at $(0, 0)$ from the graph), the translation would be left (decrease $x$) and down (decrease $y$). Counting grids: suppose Community Center is at $(2, 4)$ and Post Office at $(0, 0)$, so translation is $(x, y) \to (x - 2, y - 4)$ (or based on grid counts: left 2 units, down 4 units).
## Step2: Calculate distance
Each grid is 0.05 mile. Total grids moved: horizontal + vertical? Wait, translation is along a vector. If moving from $(2, 4)$ to $(0, 0)$, the vector is $\langle -2, -4
angle$. The distance is the length of the vector? Wait, no—if moving along a grid (horizontal/vertical), total grids: 2 (left) + 4 (down) = 6? Wait, no, the graph: Community Center is in the top-right, Post Office at bottom-left. Let's count: from Community Center (say column 2, row 4) to Post Office (column 0, row 0): 2 left (x - 2), 4 down (y - 4). Total grids: 2 + 4 = 6? Wait, no, the distance is the number of grids times 0.05. Wait, each grid is a square, so moving 2 left and 4 down, the number of grids moved (if moving along the grid lines) is 2 (horizontal) + 4 (vertical) = 6? Wait, no, the translation vector's magnitude? Wait, no, the problem says "each grid on the map is 0.05 mile"—so if the translation is, say, 2 units left and 4 units down (each unit is a grid), total distance: (2 + 4) * 0.05? Wait, no, that's for Manhattan distance. But maybe it's a vertical/horizontal? Wait, looking at the graph: Community Center is at (let's set coordinates: x from 0 - 3, y from 0 - 4). Post Office is at (0, 0), Community Center at (2, 4). So moving from (2, 4) to (0, 0): x changes by -2, y by -4. The number of grids: horizontal: 2, vertical: 4. Total distance: (2 + 4) * 0.05 = 6 * 0.05 = 0.3 mile? Wait, no, if it's a straight line, the distance is $\sqrt{(2)^2 + (4)^2} \times 0.05$, but the problem says "walk", so likely along grid lines (Manhattan distance). So total grids: 2 (left) + 4 (down) = 6. 6 * 0.05 = 0.3 mile.
(Note: Exact coordinates depend on graph, but the key is counting grids: suppose from Community Center to Post Office, you move left 2 grids and down 4 grids. Total grids: 2 + 4 = 6. Distance: 6 * 0.05 = 0.3 mile.)
# Answer:
Translation: Move left 2 units (or grids) and down 4 units (or grids) (depending on graph coordinates). Distance: $ (2 + 4) \times 0.05 = 0.3 $ mile (or based on exact grid counts from the graph: e.g., if moving 2 left and 4 down, total 6 grids, 6*0.05=0.3 mile).
