What is not a description of slope?
Gelneren [198K]

Answer:

Option (d) is wrong.

Step-by-step explanation:

Slope is:

  • rise over run
  • The rate of change of a line
  • Change in y over the change in x
  • <em><u>The ratio of vertical change  to the horizontal change. </u></em>

It can be given by mathematically as follows :

m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{and}\\\\m=\dfrac{dy}{dx}

Hence, the option which is not a description of slope is (d) "the ratio of horizontal change compared to vertical change"
