Answer:
f(x) = - [tex]\frac{2}{3}[/tex] x + 490
Step-by-step explanation:
noting that y = f(x), rearrange making y the subject
2x + 3y = 1470 ( subtract 2x from both sides )
3y = - 2x + 1470 ( divide terms by 3 )
y - - [tex]\frac{2}{3}[/tex] x + 490 , that is
f(x) = - [tex]\frac{2}{3}[/tex] x + 490
