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

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{5-7}{3-1}$

$m=\dfrac{-2}{2}$

$m=-1$

Slope of the line is -1.

Therefore, the correct option is D.

Answer 2

Answer: The exact answer is -1
