Question

What is the slope of the line passing through `(7,-2) ;(-6,7)`?

Answer 1

`"slope "=-9/13`

Explanation:

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

`•color(white)(x)m=(y_2-y_1)/(x_2-x_1)`

`"let "(x_1,y_1)=(7,-2)" and "(x_2,y_2)=(-6,7)`

`rArrm=(7-(-2))/(-6-7)=9/(-13)=-9/13`
