Alright. In this case, you will have to use the point slope formula, which is $$y -y_{2}=m(x-x _{2})$$
Plug the coordinate in to get $$y-(-2)=m(x-(7))$$

Now, we just need the slope.
Well, y = 2/5 x - 8/5 has a slope of 2/5.

FINALLY, we need to make the line parallel. To make two lines parallel, the lines have to have the same slope.
Therefore, m = 2/5

$$y+2 = \frac{ 2 }{ 5 }(x-7)$$

Clear? :)
