• J

The gradient for the line in the following diagram is:

• 5

• 2

• -2

The y-intercept of the linear graph y = −6x + 2 is:

• y = -6

• x = 2

• y = -2

• y = 2

• x = 3

Consider a linear graph that goes through the points (0, −3) and (−6, 0).

The gradient of this line is:

• -2

• 2

• 1

• 0.5

• -0.5

The rule for a line whose gradient is 2 and y-intercept = −7 is:

• y = −2x + 14

• y = 2x + 7

• y = −2x − 14

• y = 2x − 7

• y = −2x − 7

A straight line has an x-intercept of x = −3 and a y-intercept of y = 9. The gradient of this line is:

• 3

• -3

• 9
