How do i find the slope and y intercept in this scenario ?

OpenStudy (anonymous):

OpenStudy (jdoe0001):

using a "best fit line" I'd think

OpenStudy (jdoe0001):

though the y-intercept is kinda clear from the scatter plot :) now, the slope, you can always get it from the first derivatie =)

OpenStudy (jdoe0001):

derivative even

OpenStudy (dani_rose):

This will help you

OpenStudy (anonymous):

@jdoe0001 can u pls help ?

OpenStudy (anonymous):

The y intercept is (2.5, 1) ???

OpenStudy (jdoe0001):

:) rather

OpenStudy (jdoe0001):

hmmm do you know what a y-intercept is?

OpenStudy (jdoe0001):

anyhow... get a best fit line, and use that :)

OpenStudy (anonymous):

THe point where the line goes onto the y axis

OpenStudy (jdoe0001):

yeap, and if you see the graph, that point seems to be 0,0, or the origin

OpenStudy (anonymous):

okay so 0,0 is my y intercept ?

OpenStudy (jdoe0001):

well, the graph is "trending" that way, so it'll hit the y-axis there

OpenStudy (anonymous):

Okay so the slope is ?

OpenStudy (jdoe0001):

get a best fit line, and get its slope from two points

OpenStudy (anonymous):

one sec brb let me draw the line

OpenStudy (jdoe0001):

all you need is, two points from that line, to get the slope
