Answer 2

Answer:
`(35-21)/(8-4)`

Explanation:

The slope of a line equals to the difference between points' y-coordinates divided by the difference between their x-coordinates.

That is, if
`(x_1,y_1)` and
`(x_2,y_2)` are the point of a line,

Then the slope of the line is,

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

By the given diagram,

`x_1=4`,
`y_1=21`,
`x_2=8` and
`y_2=35`

Thus, the slope of the given line

=
`(35-21)/(8-4)`

⇒ Fourth option is correct.
