anyone? know? how? to? do? these?

OpenStudy (anonymous):

sorry, im lost o_o

@SolomonZelman

OpenStudy (igreen):

First we find the slope.. \(m = \dfrac{y_2-y_1}{x_2-x_1}\) Let's take the two points they give us: \((1.5, 2)\) and \((-4, -1)\) and plug them in: \(m = \dfrac{2 + 1}{1.5 + 4}\) Can you solve that? @bellaboo258

OpenStudy (igreen):

@Radelp I got it covered :)

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

hold on im finding the slope

OpenStudy (igreen):

After we find the slope, we can locate the y-intercept, and plug it into slope-intercept form, which is \(\sf y = mx + b\), then we can re-arrange it into standard form \(\sf Ax + By = C\).

OpenStudy (igreen):

Okay, @bellaboo258 tell me what you get.

@iGreen

OpenStudy (igreen):

Yes, I got the same thing.

OpenStudy (anonymous):

nowww wuut?

OpenStudy (igreen):

Now we find the y-intercept..which is where the line crosses the y-axis..and where's that?

OpenStudy (anonymous):

im like really bad at this..

OpenStudy (anonymous):

at 1? on the y axis?

OpenStudy (igreen):

Yep, that looks right.

OpenStudy (anonymous):

y=mx+b so y=mx+1?

OpenStudy (igreen):

This doesn't exactly work out..I guess we can just graph them and compare.. https://www.desmos.com/calculator/pobssrvbmh Which one do you think it is?

OpenStudy (anonymous):

C?

OpenStudy (igreen):

Nope

OpenStudy (igreen):

Look again.

OpenStudy (anonymous):

A?

OpenStudy (igreen):

No..

OpenStudy (anonymous):

than i have no i dea

OpenStudy (igreen):

You don't know which one looks most like the one on the graph they gave you?

OpenStudy (anonymous):

B

OpenStudy (igreen):

Yep, that's your answer.
