Write an equation of the line containing the given point and parallel to the given line. express your answer in the form y=mx+b

(-8,4); 9x=7y+5
y= ?

The line parallel to a line

Ax+By+C=0
and passing through point P(x1,y1)
is given by
A(x-x1)+B(y-y1)=0
You can transpose terms to put it in the form y=mx+b.
For the line
L1 : 9x=7y+5
The line L2 parallel to L1 and passing through (x1, y1) is therefore
9(x-x1) = 7(y-y1)
