Question

How do you find the slope given (1,4) and (3,2)?

Answer 1

The slope `= -1`

Explanation:

The coordinates are:
`(1,4) = color(blue)(x_1 ,y_1)`

`(3,2) = color(blue)(x_2 ,y_2)`

The slope is calculated using formula:
Slope `= color(blue)((y_2 - y_1)/ (x_2 -x_1)`

`= (2-4) / (3-1)`

`= (-2) / (2)`

The slope `= -1`
