**Parameter Elimination and Curve Sketching**

*Objective:* Sketch the curve by eliminating the parameter, and indicate the direction of increasing \( t \).

**Problems:**

(a) 
\[ x = 3t - 4, \quad y = 6t + 2 \]

(b) 
\[ x = 2\cos(t), \quad y = 5\sin(t) \quad (0 \leq t \leq 2\pi) \]

(c) 
\[ x = 2\sin^2(t), \quad y = 3\cos^2(t) \quad \left(0 \leq t \leq \frac{\pi}{2}\right) \]

---

*Instructions:* 
1. Find a relationship between \( x \) and \( y \) by eliminating \( t \).
2. Sketch the resulting curve in the \( xy \)-plane.
3. Indicate the direction in which the curve is traced as \( t \) increases.
