Answer 1

i think the answer is going to be a

Answer 2

Answer:

The correct answer is option A.

Step-by-step explanation:

Two points are given :$(x_1,y_1)(x_2,y_2)$:(-5.5, 6.1), (-2.5, 3.1)

Slope from the two point is determined by the formula :

$slope=\frac{y_2-y_1}{x_2-x_1}$

$slope=\frac{3.1-(6.1)}{(-2.5)-(-5.5)}=\frac{3.0}{-3.0}=-1$

The slope of the line that passes through the pair of points is -1.

Hence, the correct answer is option A.
