B. 1


C. 0


D. undefined

Answer 1

i think the answer is going to be a

Answer 2

The correct answer is option A.

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

`slope=(3.1-(6.1))/((-2.5)-(-5.5))=(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.
