Question 89067: find the value of k that will make the lines 2x + y = 3 and kx + y = -1 parallel

The key thing to know is parallel lines have the same slope.
So write each equation in y=mx+b form. Once you do that, m is the slope and you can equate them fr the 2 equations:
Equation #1:
Equation #2:
So now, you can just equate the 2 slopes and solve for k:
