You can find this because we know slopes that are parallel have the same slope. Since the original is just y = a number, we know the slope is 0 and therefore there will be no x. Since this next equation is parallel to that, it will also just be y = a number with no x.
Since in the new ordered pair, y = 5, that must be the equation that we use as it is also parallel.
<span>3 is 1.0 below the mean. That is 1.0 / 0.9, or 1.1111... standard deviations below the mean. So look up z < -1.11 on your graphing calculator. It should be around 0.1335 or 13.35%</span>
