Sometimes our a lines will not be written in the form:  y = mx + c

In this case, you need to use your algebra skills to solve for y.  Then you can compare gradients to find out if the lines are parallel or not.

Find out how to figure out the equation of a line when we are given a point that it passes through and the equation of a parallel line.  Once you have watched the video and read the examples, try the questions on the second page of the link above.
