Question 1126111
here's a graph of the ordered pair (-1/2, 4).

the x-coordinate is -1/2.


the y-coordinate is 4.


if you draw a vertical line at x = -1/4 and a horizontal line at y = 4, the intersection of that vertical line and the horizontal line will be the point (-1/2, 4).


of course, you only do that in your head, because it would otherwise clutter up your graph.


i normally do that only to show that the coordinate point is the intersection of the vertical line at x = -1/2 and the horizontal line at y = 4.


here's my graph of that.

the graphing software shows the intersection at (-.5, 4).


-.5 is the decimal equivalent of -1/2.


the x-coordinate is -.5.


the y-coordinate is 4.
