plz help!!!!!! Graph each of the following linear equations on the same coordinate plane and show the solution point y = -2x + 3 y = 3x - 7

OpenStudy (jdoe0001):

for each, pick two random "x" inputs to get the "y" outputs is a LINEar equation, thus it makes a line, and to plot a line, all you need is two points

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

then what?

OpenStudy (godlovesme):

@kale8282 help??

OpenStudy (anonymous):

yes plz!!

OpenStudy (anonymous):

plz help

OpenStudy (godlovesme):

give me a sec @kale8282 be back promise

OpenStudy (anonymous):

ok @Godlovesme

OpenStudy (godlovesme):

im back lolol i was helping someone and i'm done

OpenStudy (anonymous):

ok

OpenStudy (godlovesme):

so what is the y-intercept in the 1st equation?

OpenStudy (anonymous):

-2x + 3?

OpenStudy (godlovesme):

the y-intercept y=mx+b m is slope b is y-intercept so try again

OpenStudy (anonymous):

3

OpenStudy (godlovesme):

yes y-intercept is where the line hits the y-axis like this|dw:1421982010585:dw| for our graph that point is going to be 3 confused?

OpenStudy (anonymous):

ok

OpenStudy (godlovesme):

and slope is ?

OpenStudy (anonymous):

-2

OpenStudy (godlovesme):

yes -2/ 1 slope means rise/run rise is y and run is x

OpenStudy (godlovesme):

|dw:1421982158113:dw| that will be our coordinate grid

OpenStudy (anonymous):

ok

OpenStudy (godlovesme):

|dw:1421982255977:dw| since our slope is -2/1 we have to go down 2 and 1 over so far so good?
