Question

Which of the following correctly represents the slope ratio of a linear function?

Answer 1

Option (C)

Explanation:

a). Slope of a line passing through two points
`(x_1,y_1)` and
`(x_2,y_2)` is represented by the expression,

Slope =
`\frac{\text{Change in y-coordinates}}{\text{Change in x-coordinates}}` Or
`\frac{\text{Rise}}{\text{Run}}`

=
`(y_2-y_1)/(x_2-x_1)`

=
`(\triangle y)/(\triangle x)`

Therefore, slope ration of a linear function is represented by
`(\triangle y)/(\triangle x)`

Hence, Option (C) will be the correct option.
