Find the length of the perpendicular from the point negative 19, negative 13 to the π¦-axis.
If we sketch a coordinate grid with the π₯-axis and the π¦-axis and we say that this is our point negative 19, negative 13, itβs located 19 units to the left of zero and 13 units down. Perpendicular to the π¦-axis will be horizontal lines. Weβre asking the question how far away from the π¦-axis is the point negative 19, negative 13. Our point is 19 units to the left of the π¦-axis, which means we can say that its length is 19 units. We also might point out that when we have the coordinate form π₯, π¦, the perpendicular distance from the π¦-axis will always be the absolute value of π₯. Here, the absolute value of negative 19 is positive 19.
