Choose the point-slope form of the equation below that represents the line that passes through the points (−6, 4) and (2, 0). y − 4 = −one half(x + 6) y − 4 = 2(x + 6) y + 6 = −one half(x − 4) y + 6 = 2(x − 4) @ganeshie8

OpenStudy (nincompoop):

do you want to ask me?

OpenStudy (anonymous):

anyone that can help !!! O.O

OpenStudy (nincompoop):

solve for the slope

OpenStudy (nincompoop):

brb

OpenStudy (anonymous):

show me O.O

OpenStudy (nincompoop):

okay. but first, do you know anything about slope

OpenStudy (anonymous):

i know how to find it on the graph

OpenStudy (nincompoop):

okay that is fair.

OpenStudy (nincompoop):

so when we generally talk about slope, what we mean is the steepness of the line

OpenStudy (nincompoop):

if we are given the coordinates, just like the one you have it is generally in the form of (x, y)

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

i thought it was on a graph

OpenStudy (nincompoop):

let us assume that my drawing is in a cartesian graph

OpenStudy (anonymous):

ok

OpenStudy (nincompoop):

but the most important part is to be given the coordinates. once we have that, we can picture things quite easily on where they rest in the graph

OpenStudy (anonymous):

are the cordinates the numbers in the question

OpenStudy (anonymous):

(−6, 4) and (2, 0).

OpenStudy (nincompoop):

yes do you know what the cartesian graph looks like?

OpenStudy (anonymous):

OpenStudy (anonymous):

._.

OpenStudy (anonymous):

hello @nincompoop

OpenStudy (nincompoop):

so it is important to get acquainted with the proper labeling. it is not so important to have them with all of the gridlines, those are just to make it easier for us to plot things and to put where the coordinates belong

OpenStudy (anonymous):

ok
