Question

What is the slope of the line passing through the following points: `( -1, 5) , (3,-1)`?

Answer 1

The slope`=(-3)/(2)`

Explanation:

The points are:
`(-1,5) = color(blue)(x_1,y_1`
`(3,-1) = color(blue)(x_2,y_2`

The slope is found using formula:
slope `=(y_2-y_1)/(x_2-x_1)`

`=(-1-5)/(3-(-1))`

`=(-6)/(3 +1)`

`=(-6)/(4)`

`=(-3)/(2)`
