Question

2.

Find the slope of the line that passes through the pair of points.

(–5.5, 6.1), (–2.5, 3.1)

A.
`(3)/(8)`

B. –1

C. 1

D.
`-(3)/(8)`

Answer 1

B. -1

Explanation:

-1

According to the slope formula:

Slope = (y2 - y1)/(x2 - x1)

y2 = 6.1

y1 = 3.1

x2 = -5.5

x1 = -2.5

Therefore:

6.1-3.1/-5.5--2.5

Since negative negative is positive you are left with:

3/-3

Therefore the answer is -1.
