Question

A line has a slope of 4. What is the slope of any line perpendicular to this line? A −4 B −14 C 14 D undefined

Answer 1

Answer:

-1/4

Step-by-step explanation:

Perpendicular lines have slopes that multiply to -1

m * 4 = -1

Divide by 4

m = -1/4

The slope of a line that is perpendicular to a line that has a slope of 4 is -1/4

Answer 2

Answer:

-1/4

Step-by-step explanation:

The slopes of perpendicular lines are reciprocals of each other,

meaning if the slope of one line is 4 then its perpendicular lines slope is -1/4.

Thus,

its slope is -1/4.
