Answer 2

4/4=1

Answer 3

it should be -2.

Answer 4

ahh i didnt simplify

Answer 5

nono, it's the other way around, -8/4, not -4/8

Answer 6

slope : deltay / deltax

now choose (6,2) as point number one
and (10,-6) as point number two

(y1 - y2) / (x1-x2)
(2-(-6)) / (6 - 10 ) = 8 / -4 = -2

Answer 7

i thought it was x2-x1/y2-y1..??

Answer 8

no, it's the other way around.

Answer 9

no no !!!

Answer 10

dy/dx

Answer 11

so the answer is -8/4 ? not -4/8
