Answer :
I think you mean like y=mx+c
6x+5y=-15 -- subtract 6x
5y=-15-6x -- divide by 5
y=(-6x/5)-3
6x+5y=-15 -- subtract 6x
5y=-15-6x -- divide by 5
y=(-6x/5)-3
[tex]General\ equation\ for\ line\ in\ slope\ intercept\ form:\\\\y=ax+b\\\\6x+5y=-15\\
5y=-15-6x \ \ |:5\\
y=-3-\frac{6}{5}x\\\\
In\ slope\ intercept\ form\ y=-3-\frac{6}{5}x.[/tex]
