Question

if the gradient of a line (B) is -3, what is the gradient of the line which is perpendicular to (B)

Answer 1

The slope or gradient of a line is -3 (m1)

Let the slope of the other line be m2

As the lines are perpendicular

therefore

m1 X m2=-1

therefore m2=1/3

Answer 2

Answer:

Step-by-step explanation:

answer is 1/3
