Find the value of if the lines and are parallel.
I found the slope of the parallel lines but have no idea how I would find
Can anyone help please? Thank you very much!
Maybe from observing what you just did you can see that for the line
Ax + By + C = 0
the slope (assuming it's defined) is -A/B
But you don't have to see this, you can just solve the second equation for y (thus putting it into slope-intercept form), see what the slope is (it will be in terms of k) and then set that to 3/2.
