The y axis is the vertical one, the one going up and down.
They usually are not at the top.
It goes from bottom left to top right.
As the slope gets bigger the graph becomes closer to vertical - from bottom left to top right.

young is on the bottom of a number...
a vertical line is a line which is made from top to bottom or bottom to top.
Youngest at the top, oldest at the bottom, just as in nature.

The lines and spaces on a staff are numbered from the bottom to the top. So the 5th line would be the top line.
An infinite number. Each point on the line y = x, that is, the line that goes at a 45 degree angle, from bottom left to top right.
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
Draw three vertical lines, then three vertical lines underneath, usually about 1cm long. Then join the line on the top left to the bottom middle line, then join the top middle line to the bottom right line. Join the top left line to the top right line so it looks like a triangle. Then do the same to the bottom lines. Then join the bottom left line to the top left line. Then join the bottom right line to the top right line.
