Question

Which statement about the ordered pairs(-3, -3), (0,-3)and(3,-3) is not true?

Answer 1

The one that is wrong is. C. If all the x’s are different it is a function

Answer 2

(-3, -3) → x = -3 and y = -3

(0, -3) → x = 0 and y = -3

(3, -3) → x = 3 and y = -3

y are the same in all points. Therefore the points:

- lie on the graph of a horizontal line

- lie on the graph of the equation y = -3

- the slope of the line between each pair of points is 0

Your answer: C) the points do not represent a function.
