Need help with a problem solving question

[Bcogswell]

Homework Statement

Two lines given by the following pair of equations. If the lines are parallel, find the value of k.

Y-kx = -5x+9 Y+2x = 4(kx-2)

Homework Equations

Im not exactly sure what i need to do this.

The Attempt at a Solution

Like i said above, I'm not sure what i have to do to figure this out? At first i was thinking comparison but i don't think that's going to work.

This question is for a problem solving assignment our teacher gave us, so she never really taught us a strategy for it.

Any help would be appreciated :)

If two lines are parallel, they have the same slope. Try putting both equations into the form y=mx+b so that you can easily compare the two slopes...what values of k are they equal for?

Thanks, ill try that!
