Slope = (y2 - y1)/(x2 - x1)

= (1 + 7)/(9 + 3)

= 8 / 12

= 2/3


answer

2/3

To find slope, use the formula:


slope = (y₂ - y₁)/(x₂ - x₁)


Note that it doesn't matter which one you set as (₁), or (₂), but you must set them correctly. Let:


(x₁, y₁) = (9,1)

(x₂, y₂) = (-3,-7)


Set each to corresponding variables.


(-7 - 1)/(-3 - 9)


Simplify.


-8/-12


Simplify. Divide -4 from the numerator and denominator


(-8/-12)/(-4/-4) = 2/3


2/3 is the slope of the line.


hope this helps
