Answer:
[tex]y = - 11x[/tex]
Step-by-step explanation:
If y varies directly as x, then we can write the relation
[tex]y = kx[/tex]
where k is the constant of proportionality.
We substitute y=-319 when x=29.
[tex] - 319 = 29k[/tex]
This implies that:
[tex]k = \frac{ - 319}{29} [/tex]
[tex]k = - 11[/tex]
The variation equation now becomes
[tex]y = - 11x[/tex]
