The correct statement describing the approach Mick should take based on the best reasoning is:
Statement #1: Mick says he should verify that the lines have the same slope but different y-intercepts.
This is because two lines are parallel if and only if they have the same slope (the coefficient of \(x\)) but different y-intercepts (the constant term). In this case, both lines have a slope of \( \frac{2}{3} \) but different y-intercepts (7 and -2), which confirms that the lines are indeed parallel.
