Question

find the slope of (2,-2) and (0,-1)

Answer 1

\[\frac{\Delta y}{\Delta x}\]
\[=\frac{2-0}{-2-(-1)}=\frac{2}{-2+1}=\frac{2}{-1}=-2\]

Answer 2

oh. i got \[-2/1\] and didn't symplify it into -2

Answer 3

that is still wrong. it doesn't fit

Answer 4

its y2-y1 over x2-x1

Answer 5

Slope is the change in y's over the change in x's.

-1 - -2 -1 + 2 1
------- = ------ = -- = -1/2
0 - 2 -2 -2

Answer 6

i have been doing xs over ys i think

Answer 7

lol I messed mine up something awesome... i even said to do y/x and then i did x/y... my bad

Answer 8

so -2 is wrong???

Answer 9

okay. now i got 0/2

Answer 10

\[\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}=\frac{-2-(-1)}{2-0}=\frac{-2+1}{2}=-\frac{1}{2}\]

Answer 11

where did the one come from

Answer 12

a negative and a negative is a positive

Answer 13

oh my gosh. i got it. nevermind. sorry.

Answer 14
