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 thats 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?
