This is a translation and it is most easily done with the vertex from of the equation. change vertex to (-1,6): y=a(x+1)+6

brakcets: 6/(18) *180
now just calculate from left to right:
1/3 *180 = 60
2.8y+6+0.2y=5y-14
Combine like terms
3y+6=5y-14
Subtract 6 from both sides
3y=5y-20
Subtract 5y from both sides
-2y=-20
Divide both sides by -2
Y=10
