Given the points (2, 10) and (-6, 8) find the slope.

OpenStudy (anonymous):

Use the slope formula: \[m=\frac{ y _{2}-y _{1} }{ x_{2}-x _{1} }\]

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

Did you get it amina?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

It's a:\[\frac{ 1 }{ 4 }\]slope

OpenStudy (anonymous):

y2: 8 y1: 10 x2: -6 x1: 2

OpenStudy (anonymous):

You would just use these to fill in the formula that trainwrecking gave you. Then just solve it.

OpenStudy (anonymous):

Got it now?

OpenStudy (anonymous):

The slope between (9,-8) and (9,-9)

OpenStudy (anonymous):

how do u do this

OpenStudy (anonymous):

Well the slope is a straight line. I believe that the name for a slope as a vertical line is called undefined. Let me check first.

OpenStudy (anonymous):

The slope between the two points is undefined.

OpenStudy (anonymous):

so the answer is undefined

OpenStudy (anonymous):

The slope between (-4,3) and (-6,3)

OpenStudy (anonymous):

Yes. It's undefined because the slope is a vertical line. |dw:1397083890212:dw|

OpenStudy (anonymous):

thank you so much what about the second one?

OpenStudy (anonymous):

The slope between (-4,3) and (-6,3)

OpenStudy (anonymous):

Just a sec. I'm helping someone else.

OpenStudy (anonymous):

my answer is 1/3 is that right

OpenStudy (anonymous):

Let me check.

OpenStudy (anonymous):

The slope is actually zero.

OpenStudy (anonymous):

Any more?

OpenStudy (anonymous):

order pairs

OpenStudy (anonymous):

(14,5) and (18,-7) m =
