Question

find the slope,if it exists, of the line containing the pair of points (8,0) and (0,-8)

Answer 1

\[{y_2-y_1\over x_2-x_1}\]

Answer 2

slope k=y/x
y=(-8-0)=-8
x=(0-8)=-8
so k=-8/-8=1

Answer 3

is that answer simplify

Answer 4

so m=1

Answer 5

yes

Answer 6

thanks

Answer 7

:)

Answer 8

same question but (1,-7) and (-1,-7)

Answer 9

y=-7-(-7)=0
x=-1-1=-2
so k=0/-2=0

Answer 10

so does that mean the slope is undefined
