A line on a graph that compares two variables, temperature for example tells us a great deal about the relationship of these variables in the experimental system. When the line is straight it reflects a direct and proportional relationship between the two factors.
Ejnar Hertzsprung and Henry Norris Russell,working independently, realized the relationship between a star's temperature and its brightness.Together, in 1910, they formed what is now known as the Hertzsprung--Russell diagram or HR Diagram.It's a scatter graph showing the relationship between a star's absolute magnitudes, their spectral types and temperatures.
In that case, the graph would be a straight line.In that case, the graph would be a straight line.In that case, the graph would be a straight line.In that case, the graph would be a straight line.
Look at the equation for kinetic energy.It is clear that relation between mass and kinetic energy is linear (you would get a straight line on the graph), while the relation between speed and kinetic energy is quadratic (you would get a curve, specifically a parabola).
Phase diagram?
I believe that this would probably be a line graph, or a double line graph-whichever you choose to call it. It could also be a double bar graph though too.
Linear = Straight line! So, a graph of a linear relationship is a straight line.

it is a positive relationship
With very rare exceptions the solubility is higher at high temperatures,
The graph is a straight line.
Straight line.
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
A linear relationship will show up on a graph as a straight line.

A straight line which is not vertical.
