0

undefined

Answer 1

slope formula if you remember:\[\frac{ y2-y1 }{ x2-x1 }\]

Answer 2

yeh i remember

Answer 3

If you plot those points, does it make a vertical or horizontal line?

Answer 4

if it makes a vertical line: undefined

horizontal:slope of 0

Answer 5

i got -6for the slope

Answer 6

Nope. The slope is definitely either 0 or undefined.

y2-y1=9-9=o/anything=0 or undefined

Answer 7

if it makes a vertical line:
undefined horizontal:slope of 0

or if the x values change, it will be horizontal.

Answer 8

does it change here?

Answer 9

0

Answer 10

it is indeed a horizontal line, which makes the slope 0. good job.
