O A.
O B.
1
2
O c. 1
O D.-1

Answer 1

Given;

The graph of a line.

To find:

The slope of the line.

Solution:

From the given graph it is clear that the line passes through the points (1,7) and (3,5).

So, the slope of the given line is

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

`m=(5-7)/(3-1)`

`m=(-2)/(2)`

`m=-1`

Slope of the line is -1.

Therefore, the correct option is D.
