Question

The ordered pair (a, b) gives the location of point P on the coordinate plane. The value of a is zero and the value of b is not zero. Where could point P be located on the coordinate plane?
Select one or more:
x-axis
Quadrant IV
y-axis
Quadrant I
Quadrant II
Quadrant III

Answer 1

Since a is 0, it must be on the y-axis. It could also be on the x-axis if b is 0.

So the answer is x-axis and y-axis :).

Answer 2

y-axis, a coordinate pair is (x,y) so when x = 0 the point must be on the y-axis.
