Question

Find the slope of line passing through the points (5, 9) and (5, -2)

(A)-11
(B)0
(C)11
(D)undefined

Answer 1

\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]but when you try plug in and solving it...
numerator: -2 - 9 = -11
denominator: 5 - 5 = 0
you cannot have a 0 in the denominator
therefore the slope is undefined

Answer 2

thanks!! can u plz help me with one more???

Answer 3

sure :)

Answer 4

thanks :)

Find the slope of line passing through the points (4,8) and (6, -2).

Answer 5

1/5
5
-1/5
-5

Answer 6

you can use the same slope form as before :)
\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]so in numerator: -2 - 8 = -10
in denominator: 6 - 4 = 2
so you get -10/2 =

Answer 7

so its -1/5 right? sry my brain is fried lolz

Answer 8

negative 10 divided by 2 equals negative 5

Answer 9
