Question

How do you find the slope of `(-9, -3), (-7, -5)`?

Answer 1

`"slope "=-1`

Explanation:

To calculate the slope use the `color(blue)"gradient formula"`

`color(red)(bar(ul(|color(white)(2/2)color(black)(m=(y_2-y_1)/(x_2-x_1))color(white)(2/2)|)))`
where m represents the slope and `(x_1,y_1),(x_2,y_2)" 2 coordinate points"`

The 2 points here are (-9 ,-3) and (-7 ,-5)

let `(x_1,y_1)=(-9,-3)" and " (x_2,y_2)=(-7,-5)`

`rArrm=(-5-(-3))/(-7-(-9))=(-2)/2=-1`
