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=
`(y2-y1)/(x2-x1)`
M=

M=
`(-5)/(5+4)`
M=
`(-5)/(9)`


answer is C -5/9
