Question

How do you find the slope of a line segment connecting points A(4,-5) and B(-5,8)?

Answer 1

`"slope "=-13/9`

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)=(4,-5)" and "(x_2,y_2)=(-5,8)`

`rArrm=(8-(-5))/(-5-4)=13/(-9)=-13/9`
