Find the equation of a line parallel to 4x-y=-3 that contains the point (-1,-2). write the equation in slope intercept form. Please show work. I have a hard time understanding these problems.

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.
