When A ∝ B, the graph is a straight line passing through
Select the correct graphs
a) The P-V graph at constant temperature is a rectangular hyperbola.
b) The P-V graph is a straight line parallel to the Y-axis.
c) P-V graph at constant temperature is a straight line passing through the origin
d) V-T graph at constant pressure is a straight line passing through the origin.
If the velocity-time graph is some straight line in a plane passing through origin, then definitely
