Four students investigated the correlation between variable $x$ and variable $y$ based on their respective sample data. They obtained the linear regression equations and correlation coefficients $r$, and arrived at the following four conclusions:
$①y=2.347x-6.423$, with $r=-0.9284$;
$②y=-3.476x+5.648$, with $r=-0.9533$;
$③y=5.437x+8.493$, with $r=0.9830$;
$④y=-4.326x-4.578$, with $r=0.8997$.
Determine the sequence number(s) of the incorrect conclusion(s).
