When you are reading a grid coordinate, always read _____ first, then _____.

When reading a grid coordinate, the conventional method involves reading the horizontal position before the vertical position. Therefore, you would read the coordinate by first determining the value along the horizontal axis, which is typically represented as right or left on a map or grid. After identifying the horizontal position, you then move vertically to identify the corresponding value, which is either up or down.

This method ensures that you accurately pinpoint a location within the grid system, as the coordinates are set in a manner that the first value refers to the x-axis (horizontal) and the second value to the y-axis (vertical). This systematic sequence is essential for navigating maps or grids effectively, as reversing the order could lead to significant errors in location identification. The correct answer reflects this standard practice in coordinate reading.
