Question

What is the slope of the line passing through the following points: `(-10,-5) , (-8,-7)`?

Answer 1

slope = - 1

Explanation:

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

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

The 2 points here are (-10 , -5) and (-8 ,-7)

let `(x_1,y_1)=(-10,-5)" and " (x_2,y_2)=(-8,-7)`

`rArrm=(-7-(-5))/(-8-(-10))=(-2)/2=-1`
