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

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

@jdoe0001 can u pls help ?

The y intercept is (2.5, 1) ???
OpenStudy (jdoe0001):
:) rather
OpenStudy (jdoe0001):
hmmm do you know what a y-intercept is?

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

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
