Question

What is the slope of the line through (-1,8) and (3,-4)?

Choose 1 answer:
A)-1/3
B)-3
C)1/3
D)3

Answer 1

The answer is option B

Explanation:

The slope of a line given two points can be found by using the formula

`m = ( y_2 - y _ 1)/(x_ 2 - x_ 1) \\`

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-1,8) and (3,-4)

The slope is

`m = ( - 4 - 8)/(3 - - 1) = ( - 12)/(4) = - 3 \\`

We have the final answer as

- 3
