To solve this problem you must apply the proccedure shown below:
1- You have that the equation of the line is:

Where
is the slope and
is the y-intercept.
2- Based on the information given in the problem, the lines
and
are parallel, which means that both have the same slope. Therefore, you can calculate the slope of
:


3- Use the coordinates of the point
to calculate the y-intercept:

4. Solve for
:

5. The equation of the line
is:

The answer is: 
The answer is -5x + 4y = -20
2+2=4
a^2+b^2=c^2
15^2-4^2
=225-16
=209
Lying in the same straight line i think..
