# Pls answer assertion reason

In order to have a straight line between P and Q, both these physical quantities must satisfy the straight line equation:

$P=mQ+c\phantom{\rule{0ex}{0ex}}where,\phantom{\rule{0ex}{0ex}}ccanbetheintercept.\phantom{\rule{0ex}{0ex}}mistheslopewhichiscons\mathrm{tan}t\phantom{\rule{0ex}{0ex}}forc=0\phantom{\rule{0ex}{0ex}}P=mQ\phantom{\rule{0ex}{0ex}}Thus,P\propto Q(\mathrm{sin}ce,misacons\mathrm{tan}t)\phantom{\rule{0ex}{0ex}}form=1\phantom{\rule{0ex}{0ex}}P=Q$

For a straight line dependence,

$\frac{P}{Q}=cons\mathrm{tan}t\phantom{\rule{0ex}{0ex}}PQ\ne cons\mathrm{tan}t$

Thus, the statement is FALSE but the reason is TRUE.
