Well, for starters, if 2 lines are parallel what does that tell you about their slope? (The slope is the gradient)

y=mx+b is the gradient and y intercept form of a line. m is the gradient. b is the y intecept.

So how about you add some input at this point. What can you tell me about this line that you need. ???

Hello **Lt_Soul**,

We are searching a line*e: y=mx+b*.

If e(line) parallel to y=2x+5 then the two lines have the same Slope! So m=2.

Also, if the point A(-7, -9) we can easy find b:

*(y-y*_{A})=m(x-x_{A}) => (y-(-9))=2*(x-(-7))

We are searching a line

If e(line) parallel to y=2x+5 then the two lines have the same Slope! So m=2.

Also, if the point A(-7, -9) we can easy find b:

(y-(-9))=2*(x-(-7))

Finally, the line which is parallel to*y=2x+5* and passes through the point (-7, -9) is the line *y=2x+5*
