If its a Cartesian co-ordinate system then the two axis are orthogonal.
A graph of Charles' Law shows the relationship between Volume vs. Temperature. Volume is placed on the y axis and temperature on the x axis. The relationship is linear if temperature is in units of Kelvin.
the relationship between two variables
the tilt of earths axis relative to the sun.
positive linear relationship
Graphs showing the relationship (or not) between two independent variables.
Yes.
Graphically, the conjugate of a complex number is its reflection on the real axis.
The greater the distance from the axis of rotation (i.e., pivot point) to the center of gravity of an object, the greater the torque required to rotate the object.
The axial tilt of the earththe tilt of earth's axis relative to the sun
bar graph It's actually line graph. (I just learned this at school.)
The major importance of a line graph is that it allows a person to visually see the relationship between two major variables. A line graph contains a vertical axis and a horizontal axis.
