Ok, you already know that the y-intercept is 9. Now you need to find the slope, because parallel lines always have the same slope. You do this using this formula:

So plug in the values:

Subtract:
or

Now you know the slope, and the y-intercept, . Now you put these values into a slope-intercept form equation to get your answer:
y=4/7x+9

To check, insert the x and y values of the only known coordinate on this line, which is (0,9).
9=4/7(0)+9

Multiply:
