Answer 2

Option A and D

Explanation:

If a line passes through two points
`(x_1,y_1)` and
`(x_2,y_2)`, then the slope of the line is

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

In option A, the function passes through the points (3,-11) and (6,1). So, the slope of the linear function is

`m_A=(1-(-11))/(6-3)=4`

In option B, the function passes through the points (0,3) and (9,5). So, the slope of the linear function is

`m_B=(5-3)/(9-0)=(2)/(9)`

In option C, the function passes through the points (-5,32) and (-1,24). So, the slope of the linear function is

`m_C=(24-32)/(-1-(-5))=-2`

In option D, the function passes through the points (2,0) and (4,8). So, the slope of the linear function is

`m_D=(8-0)/(4-2)=4`

Therefore, the correct option are A and D.
