how do you graph systems of equations

OpenStudy (anonymous):

Place each in mx+b form

OpenStudy (anonymous):

i dont know how

OpenStudy (anonymous):

give me example, and I show you that way

OpenStudy (anonymous):

x+y=18

OpenStudy (anonymous):

Okay, you place x over on one side. y=-x+18. so, m=-1, and b = 18

OpenStudy (anonymous):

ok but what the slope and y intercept

OpenStudy (anonymous):

Okay, slope is simply rise over run. In this case, the rise (or, how high you go in the y direction) is down 1. The run (or how far you go in the x direction) is to the right 1. the y intercept is where the line cuts the y axis.

OpenStudy (anonymous):

so 1/1

OpenStudy (anonymous):

yes sir, boss man/woman

OpenStudy (anonymous):

twhats the x intercept

OpenStudy (anonymous):

No, that's where you can take any point, usually the y intercept, and go down on, and to the right one.

OpenStudy (anonymous):

ok but i have two the other one is 3x-y=10

OpenStudy (anonymous):

okay, so, get y by itself. so, it'll look like y=3x-10. Now, try to make line with that :)

OpenStudy (anonymous):

y=10 x= 3.33

OpenStudy (anonymous):

No, keep everything in y=mx+b form. So, the slope is 3/1, and the y intercept is (0,-10)

OpenStudy (anonymous):

okee i am really bad at this and my math teacher is really mean we had a sub so and this is some stuff i really dont understand

OpenStudy (anonymous):

how do you graph 80x+40y=400 and 20x+80y=420
