1One of the two humans inside said something about the x-axis.
2Schematic illustration of increasing mutation rates (x-axis) resulting from antimicrobial selection pressure.
3Here the x-axis is in the direction of R2's motion.
4The sum of torques about the x-axis must be zero.
5In two dimensions, there is an x-axis and a y-axis.
6Now I can call my position along the x-axis.
7On a graph, is the x-axis vertical or horizontal?
8This is looking down the 'x-axis' I left some stuff off, but hopefully that will help.
9On the x-axis is age (in millions of years) and relative probability on the y-axis.
10It's two bog-standard x-axis, y-axis graphs.
11You put the effect (i.e., how effective the treatment is) on the x-axis, from left to right.
12Let's look at the vector A from above: I added the angle that this vector is above the horizontal (or x-axis).
13This is the horizontal (x-axis) motion of my guess for Simpson's center of mass (which I approximate as being around his waist).
14You could also find the "direction" of this vector and say that it is 33.7° below the x -axis.
