The gradient of the line passing through the points A(–3, 4) and B(2, –6) is:

1. –$\dfrac{1}{2}$

2. –2

3. 2

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

The equation of a straight line whose inclination with x-axis is 30° and whose y-intercept is –4, is:

1. $\sqrt{3}x - y - 4\sqrt{3} = 0$

2. $x + \sqrt{3}y - 4\sqrt{3} = 0$

3. $x - \sqrt{3}y - 4\sqrt{3} = 0$

4. $\sqrt{3}x + y - 4\sqrt{3} = 0$

The inclination of the line y = $\sqrt{3}$ x – 5 is:

1. 0°

2. 30°

3. 45°

4. 60°

If the slope of the line passing through the points (2, 5) and (k, 3) is 2, then the value of k is:

1. 0

2. –1

3. 1

4. 2
