Question

find the gradient that is perpendicular to a line with gradient minus 3​

Answer 1

Answer:

perpendicular gradient = $\frac{1}{3}$

Explanation:

In parallel, the gradient is same. m1 = m2

using formula: m1 * m2 = -1

         solve:

• -3 * m2 = -1

• m2 = $\frac{-1}{-3}$

• m2 = $\frac{1}{3}$
