Solution
The correct option is B (0, –4)
Coordinates are ordered pairs of numbers.
The first number indicates the point on the x-axis and the second the point on the y-axis.
To find the coordinates of Jennifer's school, we first start at the origin and count the number of steps we move in the x-direction and then in the y-direction to reach the school.
We observe that the school lies on the y-axis. So, its x coordinate will be 0.
Since we move exactly 4 steps down the origin on the y-axis to reach the school, its y coordinate is –4.
Hence, the coordinates of the school are (0, –4).
