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