Yes. Let me know what you come up with and I'll let you know if you are correct.

So far I came up with

y+7 = 4/5(x-0)

Now I am stuck...

OK, you could do it that way, and distribute the 4/5 and subtract the 7:

y=4/5x-0-7

y=4/5x-7.

Or, you could just start with y=mx+b. If you didn't notice, the point they gave you was the y-intercept because the x-value was 0, meaning that was where the line crosses the y-axis. So, since b is the y-intercept, you could have just immediately written

y=4/5x-7
