Question

Find the distance of point (8, −4) from y-axis.

Answer 1

Given:

Point coordinates are (8, −4)

Formula:

Distance of a point (x, y) from the y-axis = |x|

Solution:

Distance from y-axis = |8|  [Substituting the x-coordinate of the given point into the distance formula]

Distance from y-axis = 8  [Evaluating the absolute value]

∴ 8 units
