Question

What is the slope of the line that contains these

points?
X=

-1 1
3
5

у=

10
2
-6
-14

Answer 1

The slops is -4

Explanation:

Given

x: -1 1 3 5

y: 10 2 -6 -14

Required

The slope

Pick any pair of x and y

`(x_1,y_1) = (-1,10)`

`(x_2,y_2) = (1,2)`

The slope is:

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

`m = (2 -10)/(1 --1)`

`m = (-8)/(2)`

`m = -4`
