The name of the point (0, 0) on a number (Cartesian) plane is:

• y-intercept

• gradient

• origin

• axis

Which point is not in line with the other points?

A(-2, 3), B(-1, 2), C(0, 0), D(1, 0), E(2, -1)

• A

• B

• C

• D

• E

Which of the points A(1, 2), B(2, -1) or C(3, -4) lie on the line y = -x + 1?

• C

• A and C

• A

• B
