pls help The graph below shows a line segment AB: Graph of line segment AB with endpoints at negative 2 comma 2 and 4 comma negative 1 What is the slope of the line segment AB?

OpenStudy (snowwolfx2):

why

OpenStudy (vulgarutensils):

what do you mean?

OpenStudy (mathmale):

This is a legitimate question. V-u: kindly write your 2 points in the form (x,y) and then use the "slope formula" to find the slope of the line segment connecting these two points.

OpenStudy (mathmale):

Look up "slope formula" on the 'Net if you're not 100% sure you already know it.

OpenStudy (3mar):

Sorry for late. Still need help?

OpenStudy (vulgarutensils):

Yeah.

OpenStudy (3mar):

Do you have the graph or want to draw it?

OpenStudy (vulgarutensils):

one second.

OpenStudy (vulgarutensils):

OpenStudy (3mar):

It is away better now, although we can draw it as we have been given the above data. Anyway... Do you know the form of the slope of a line?

OpenStudy (vulgarutensils):

m=y2-y1/x2-x1

OpenStudy (3mar):

Excellent! Can you assign two points from the graph of the line through them the line passes?

OpenStudy (vulgarutensils):

(-2,2) and (4,-1)

OpenStudy (3mar):

I don't think so. These are three points. Pick two of them and plug them into the formula of the slope!

OpenStudy (vulgarutensils):

Could I chose those two points?

OpenStudy (vulgarutensils):

\[\frac{ 2--1 }{ -2-4}\]

OpenStudy (vulgarutensils):

hello?

OpenStudy (3mar):

Sorrrrryyyyyyy

OpenStudy (3mar):

"Could I chose those two points? (-2,2) and (4,-1)" No, because the line does not pass through them. Agree?

OpenStudy (vulgarutensils):

So i have to choose the middle one? I'm very confused.

OpenStudy (3mar):

Welcome back! Not have to. Just pick any two points that the line passes through to calculate its slope!

OpenStudy (vulgarutensils):

(1,-1) and (0,2)

OpenStudy (3mar):

1 min please

OpenStudy (vulgarutensils):

Look I don't have a lot of time left.

OpenStudy (3mar):

Yes, correct! (1,-1) and (0,2) \[m=\frac{ y_2-y_1 }{ x_2-x_1 }=\frac{ 2-(-1) }{ 0-1 }=\frac{ 3 }{ -1 }=-\frac{ 3 }{ 1 }=-3\] That is the slope of your line! I hope I helped you. +Sorry for late.
