### Mathematics Worksheet: Coordinate Geometry and Equation Solving

---

#### Distance, Midpoint, and Triangle Properties

1. **Find (a) the distance d(P,Q) and (b) the coordinates of the midpoint M of line segment PQ. Write the answer as a simplified radical.**
   - P(−3, 4) Q(6,−2)

2. **Determine whether the three points are vertices of a right triangle.**
   - P(−4, 3), Q(2, 5), R(1,−6)

#### Graphing Linear Equations

3. **Graph by plotting points. Use x = 0, 2, −2.**
   - \( y = \frac{1}{2} x + 3 \)

4. **Graph by plotting points. Use x = −2,−1, 2.**
   - \( y = \sqrt{x + 2} \)

#### Function Evaluation

5. **Let f(x) = −x² − 3x + 5. Find f(3).**

6. **Let g(x) = −2x + 5. Find g(x+3).**

#### Writing Equations of Lines

For questions #7–11, write an equation of the line with the given conditions. You may write your answer in \(y = mx + b\) or \(Ax + By = C\) form, or in \(x = a\) or \(y = b\) form, when applicable.

7. **Through (−3, 5); Slope = −2.**

8. **Through (5, −2); Slope = 0.**

9. **Slope = \(\frac{2}{3}\); y-intercept (0,−4).**

10. **Undefined slope; Through (5, 2).**

11. **Parallel to 2x + 4y= 9; Through (6, 1).**

#### Slope and Intercept Identification

12. **Find the slope, m, and y-intercept, b, of the following equation: 2x + 3y = 9.**

#### Solving Equations

For questions #13-18, you must solve each equation using the method stated in the problem. Show work to receive credit.

13. **Solve the equation by Factoring and the Zero
