Y axis is the vertical axis
X axis is the horizontal axis
you learn it
A graph has both an x and y axis.
you are correct!
The value that you manipulate (change) goes on the x-axis. This is also known as the independent variable. :)
You can determine which variable that goes on the x axis on a line graph by checking the number that comes first in a set of pair or from table, e.g [2,4]. 2 will be on the x axis because it is the first number in the pair
X-axis shows increment when is goes up and y-axis show an increment when it goes further to the right side of the graph
(x,y). x axis first, the one that goes horizantial. Then your y axis, which is the vertical one
To determine the direction of a vector, you can use trigonometry. Find the angle the vector makes with the positive x-axis using the arctangent function. This angle represents the direction of the vector in relation to the x-axis.
Yes, that is correct.
The variable that goes on the x axis is the independent variable. For example if you were measuring time and plant growth you would put time on the x axis, because the time is independent and doesn't depend on the plan growth.
You need to tell us what it is about the gas that you are measuring. Time on x-axis is correct.
Extend the line until it hits the x axis and that is the x intercept. If the line is not parallel to the x axis, then extending it one way will reach the x axis, the other way will not. If the line is parallel to the x axis it will never meet it (or, if you like, it will meet it at plus or minus infinity, which is another way of saying never).
