The gradient of a line is -1. It is also known that a point (0, -3), lies on the line. The rule for the line is:

• y = -x - 3

• y = -x + 3

• y = x - 3

• y = -3x + 1

Calculate the rule for the coordinates: (0, -5), (1, -2), (2, 1).

• y = -2x - 5

• y = -3x + 2

• y = 3x - 5

• y = 2x + 3

• 2

• -0.5

Identify the equation of this line.

• y=3x-2

• y=1/2x+3

• y=2x+3

Identify the rule for this pattern set.

• y=3x

• y+2

• y=2x+1

• y=2x+3
