To find a line that is perpendicular to the line given by the equation \( y = -3x + 5 \), we need to determine the slope of the given line and then find the negative reciprocal of that slope.

1. The slope of the given line \( y = -3x + 5 \) is \(-3\).
2. The negative reciprocal of \(-3\) is \(\frac{1}{3}\).

Now, we look for a line whose slope is \(\frac{1}{3}\).

Among the options provided, we can identify the equation that has this slope:

- \( y = \frac{1}{3}x + 9 \) (This has the correct slope of \(\frac{1}{3}\))

The other options have different slopes, so the line perpendicular to \( y = -3x + 5 \) is:

**y = \(\frac{1}{3}x + 9\)** (y equals Start Fraction 1 over 3 End Fraction x plus 9).
