If the lines 2x + 3y = 5 and kx - 6y = 7 are parallel, then the value of k is

1. 4

2. -4

3. $\dfrac{1}{4}$

4. -$\dfrac{1}{4}$

If the line 3x - 4y + 7 = 0 and 2x + ky + 5 = 0 are perpendicular to each other, then the value of k is

1. $\dfrac{3}{2}$

2. $-\dfrac{3}{2}$

3. $\dfrac{2}{3}$

4. $-\dfrac{2}{3}$

Write down the gradient and the intercept on the y-axis of the line 3y + 2x = 12.

If the equation of a line is y = $\sqrt{3}x + 1$, find its inclination.
