Linear Non-Linear Graph

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

Which of the following rules will not yield a linear graph?

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

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

• y = −3x + 9

• y = −3x − 9

• y = 3x + 9

Which of the options would not be a member of the family of curves defined by:y = 2x + 1y = 3x + 1y = 4x + 1 …?

• y = –2x + 1

• y = x + 1

• y = 2x

• y = 5x + 1

• y = 6x + 1

The solution to the simultaneous equations y = 6x + 3 and y = –6x + 3 is:

• (0, 3)

• (3, 0)

• (0,6)
