Question

If the gradient of line A is 4 what is the gradient of the line which is perpendicular to A

Answer 1

Answer:

perpendicular slope = - $\frac{1}{4}$

Step-by-step explanation:

given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$

the given slope m = 4, hence

$m_{perpendicular}$ = - $\frac{1}{4}$

Answer 2

Given that the gradient of line A the gradient of the line perpendicular to the line A, is $-\dfrac{1}{4}$.

How can gradient of perpendicular lines be found?

The gradient of a line is m the gradient of the line that is perpendicular to the given line is $\mathbf{-\dfrac{1}{m}}$.

Therefore;

The gradient of the given line, A = 4

Therefore;

The gradient of the line perpendicular to line A is $\underline{-\dfrac{1}{4}}$
