Question

M = y2 - y1 / x2 - x1 What is the slope of line JK? A) 5/9 B) 9/5 C) -5/9 D) -9/5

Answer 1

The slope of JK is 5/9

Answer 2

So
(x,y)

J is -4 to the right and 2 up so
(-4,2)

K is 5 to the right and -3 up
(5,-3)

(x,y)

x1=-4
y1=2
x2=5
y2=-3

M=$\frac{y2-y1}{x2-x1}$
M=$\frac{-3-2}{5-(-4)$
M=$\frac{-5}{5+4}$
M=$\frac{-5}{9}$


answer is C -5/9
