Question

fuzzybird · Answer

here is the graph

the points are (0,-4) and (1,3)

also (0,0) and (-1,3)

and (0,2) (0,6)


my answer for the first one would be 1/7
my answer for the second one is -1
my answer for the third one is undefined.

sooobored · Answer

$$m= \frac{y_2 -y_1}{x_2-x_1}$$

sooobored · Answer

first one seems flipped,
2nd one seems wrong
3rd one seems fine

fuzzybird · Answer

for the first one it would be 7/1 then?

sooobored · Answer

7/1 = 7
yes i agree with that

fuzzybird · Answer

okay. so the second one seems wrong, let me re-try.

fuzzybird · Answer

ah wait I believe it might be a -2.

desmarie · Answer

the first one is 7
the second one is -3
the third one is undefined I believe

sooobored · Answer

closer but still wrong...

sooobored · Answer

$$m=\frac{3-0}{-1-0} = \frac{3}{-1} = -3$$

sooobored · Answer

since the answer is already given at this point

fuzzybird · Answer

so the second one would be a -3.

Thank you both.


desmarie I apologize I cannot medal you both. :(
