Question: In coordinate geometry, what is the slope of a line that is perpendicular to a line with a slope of -3?

Options:

Correct Answer: 3

Solution:

The slope of a line perpendicular to another is the negative reciprocal. The negative reciprocal of -3 is 1/3.

In coordinate geometry, what is the slope of a line that is perpendicular to a line with a slope of -3?

In coordinate geometry, what is the slope of a line that is perpendicular to a line with a slope of -3?

Slope of a Line – The slope of a line in coordinate geometry represents its steepness and direction, calculated as the change in y over the change in x.
Perpendicular Lines – Two lines are perpendicular if the product of their slopes is -1, meaning the slope of one line is the negative reciprocal of the other.
Negative Reciprocal – The negative reciprocal of a number 'm' is calculated as -1/m, which is used to find the slope of a line perpendicular to another.
