The correct statement that describes the approach Mick should take is Statement #1: "Mick says he should verify that the lines have the same slope but different y-intercepts."
This is because parallel lines have the same slope, which means they will rise or fall at the same rate, but they will not intersect, so they must have different y-intercepts. In the given equations:
- For \( y = 23x + 7 \), the slope is 23 and the y-intercept is 7.
- For \( y = 23x - 2 \), the slope is also 23 but the y-intercept is -2.
Since both lines have the same slope (23) and different y-intercepts (7 and -2), this confirms that the lines are indeed parallel.
