Question

How do you find the slope given (8,7) (2,-1)?

Answer 1

`"slope "=4/3`

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)" are 2 coordinate points"`

`"the 2 points here are " (8,7)" and " (2,-1)`

`"let " (x_1,y_1)=(8,7)" and " (x_2,y_2)=(2,-1)`

`rArrm=(-1-7)/(2-8)=(-8)/(-6)=4/3`
