Question

What is not a description of slope?

rise over run
the rate of change of a line
change in y over the change in x
the ratio of horizontal change compared to vertical change

Answer 1

Option (d) is wrong.

Explanation:

Slope is:

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

It can be given by mathematically as follows :

`m=(y_2-y_1)/(x_2-x_1)\\\\\text{and}\\\\m=(dy)/(dx)`

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