1.

The straight line through the points R(4, 0) and S(-2, 1) has gradient:

1/6

2/3

-1/6

2.

The straight line through points A(6, 2) and B(4, -1) has gradient:

3/2

1/2

3.

Find the midpoint of A(-7,4) and B(3,-2).

(-2,3)

(-2,1)

(-5,1)

4.

Find the equation of the straight line parallel to 2y = 3x - 7 and passing through (0.5, -1).

4y = 6x - 7

4y = 6x + 1

2y = 6x - 5

5.

Calculate the distance between A(-2, -3) and B(3, -4).

6.

and

7.

The line with equation 3y - 7x + 4 = 0 has gradient:

-7/3

7/3

3/7

8.

The line with equation 3x + 2y = 5 has gradient:

-2/3

5/2

-3/2

9.

A line perpendicular to the y - axis has an equation in the form:

y = kx (k is a constant)

y = k (k is a constant)

x = k ( k is a constant)

10.

A line with equation y = mx + c is perpendicular to a line with equation y = px + q if:

p = -1/m

p = 1/m

p = -m
