OK I have been sitting here for 30 minutes trying to figure this out, can anyone point me in the right direction? Find the slope of the line passing through the points (0, 5) and (0, –1).
A)0
B)1
C)–6
D)Undefined

lets use the following notation.
0=x1(the first x of the point)
5=y1
0=x2
-1=y2
this is how to find the slope
y2-y1/x2-x1
-1-5/0-0=
-6/0 since your line hits a point and another point directly above it, it doesn't move forward. it is undefined since the slope
is a number divided by zero

ok, the slope of a line is rise/run. and rise is the difference in y values and run is difference in x values.
so in this case, rise would be (-1 - 5) and run would be (0-0)
so u get division by 0, which is undefined.
ok, if u get undefined values, that means that the 2 points are on on a vertical line. they both have the same x values, but one of their y values is higher than the other.

The line is a vertical line going through x = 0. That's an undefined slope, since slope is (change in y) / (change in x) and the change in x is 0.

Undefined since 5 - (-1) / 0 - 0 = 6/0.

You must use the slope formula.
Let m = slope.
m = (y2 - y1)/(x2 - x1)
m = (-1 - 5)/(0 - 0)
m = -6/0
Since division by zero does not exist, then there is no slope here. We say that the slope for the given points is UNDEFINED OR does not exist.
