you have 2 points, define the slope and use a point slope format

OpenStudy (amistre64):

well, if you know how to work a system of equations sure, then that way would work

OpenStudy (amistre64):

but you havent used the points correctly

OpenStudy (amistre64):

if we use the form y = mx + b, this is called slope intercept form, since it uses the slope (m) and the y intercept (b) to form the equation

OpenStudy (amistre64):

do we know what the y intercept is? can we determine the slope?

OpenStudy (anonymous):

oh yeah I mixed up the formulas

OpenStudy (anonymous):

y = -2

OpenStudy (anonymous):

yeah we could determine the slope

OpenStudy (amistre64):

y = mx - 2 its a start

OpenStudy (amistre64):

whats out slope?

OpenStudy (amistre64):

*our

OpenStudy (anonymous):

2/3 I think cause it rises up twice and goes over 3 times

OpenStudy (amistre64):

very good, so there we have the equation of a line in slope intercept form y = 2/3 x - 2

OpenStudy (amistre64):

yes

Thank you!! :)
