1. **State the problem:** Determine whether each given point lies on the specified line by substituting the point's coordinates into the line's equation and checking if the equation holds true.
2. **Recall the rule:** A point $(x_0,y_0)$ lies on the line defined by an equation if substituting $x=x_0$ and $y=y_0$ satisfies the equation.
3. **Solve each part:**
**a.** Check if $(3,0)$ lies on $y=3x$.
Substitute $x=3$, $y=0$:
$$0 \stackrel{?}{=} 3 \times 3 = 9$$
False.
**b.** Check if $(1,-6)$ lies on $y = x - 7$.
Substitute $x=1$, $y=-6$:
$$-6 \stackrel{?}{=} 1 - 7 = -6$$
True.
**c.** Check if $(1,4)$ lies on $x + 2y = 9$.
Substitute $x=1$, $y=4$:
$$1 + 2 \times 4 = 1 + 8 = 9$$
True.
**d.** Check if $(0,0)$ lies on $2x - 3y = 0$.
Substitute $x=0$, $y=0$:
$$2 \times 0 - 3 \times 0 = 0$$
True.
**e.** Check if $(1,-1)$ lies on $4x - y + 1 = 0$.
Substitute $x=1$, $y=-1$:
$$4 \times 1 - (-1) + 1 = 4 + 1 + 1 = 6 \neq 0$$
False.
**f.** Check if $(2,0)$ lies on $3x - 4y + 1 = 0$.
Substitute $x=2$, $y=0$:
$$3 \times 2 - 4 \times 0 + 1 = 6 + 0 + 1 = 7 \neq 0$$
False.
4. **Summary:**
- a: False
- b: True
- c: True
- d: True
- e: False
- f: False
This method ensures you verify each point by direct substitution and comparison.
