point slope form means (y-y1)=m(x-x1)

so u need to find the slope gradient from those 2 points

m=y2-y1/x2-x1

=-6-6/11-7

=-12/4

=-3

and finally x1,y1=7,6

(y-y1) =m(x-x1)

(y-6) =-3(x-7)

What is the slope of the line passing thtough the points A(7, -6) and B(-4, -3)?

adelina 88 [10]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points A(7, -6) and B(-4, -3). Substitute:

$m=\dfrac{-3-(-6)}{-4-7}=\dfrac{3}{-11}=\boxed{-\dfrac{3}{11}}$
