OpenStudy (zzr0ck3r):
(y_2-y_1)/(x_2-x_1) = (5-5)/(-4-5) = ?
OpenStudy (anonymous):
0/-9?
OpenStudy (zzr0ck3r):
or think about what a slope would have to be, if the function is linear, for it to pass through the same y point (5) more than once.
OpenStudy (zzr0ck3r):
0/-9 = ?
OpenStudy (anonymous):
9

what is 0/1?
OpenStudy (anonymous):
-1?
OpenStudy (zzr0ck3r):
0/anything = 0
OpenStudy (zzr0ck3r):
unless its 0/0 but dont worry about that
OpenStudy (zzr0ck3r):
so 0/1 = 0
0/2 = 0
0/9 = 0
whats 0/-9 = ?

OpenStudy (anonymous):
now can you help me find the slope of this -4,1 and -2,-3
OpenStudy (zzr0ck3r):
remember what slop is rise/run and since the two points have a y value of 5 there is 0 rise and 0 over anything is 0
OpenStudy (anonymous):
so the answer is 0?

yes
OpenStudy (anonymous):
no it shows that its not it
OpenStudy (anonymous):
-4,1 and -2,-3???
OpenStudy (zzr0ck3r):
? you sure its the right question?
OpenStudy (anonymous):
promise

OpenStudy (anonymous):
-4,1 is the rise and -2, -3 is the run
OpenStudy (anonymous):
what about (9, -6) and (5, 10)
OpenStudy (zzr0ck3r):
10--6/5-9
16/-4 = -4
OpenStudy (zzr0ck3r):
the book is wrong then
OpenStudy (zzr0ck3r):
first off the slope will be one number not 4
