draw a graph that represents the solution to the given system? 1. y = –x + 2 y = 3x – 1
It turns out so ugly :D
Just draw the graphs for both equations on same coordinates and find the solution at the intersection of the two lines

thankyou soo much :)
draw a graph that represents the solution to the given system? can you help with this one –4x + 3y = –12 –2x + 3y = –18
First, write it as y = mx + b
Can you do that?
ya i think so
now what
do you graph it or put y on both sides haha i kinda forgot it its been awhile
You have y alone on one side and should be able to easily "see" the graph. m is the slope and b is where the line will start..
im sorry i still dont understand
|dw:1339007008950:dw|
m is the slope. Which means when you move one unit on the x-axis, you will move m units on the y-axis
b is where on the y-axis the line starts
|dw:1339007173069:dw|
in this case, m = 2, where you move twice for each on the x-axis
–4x + 3y = –12 => 3y =-12+4x => y = 4/3x-4 –2x + 3y = –18 => 3y = -18+2x => y = 2/3x+6
i get it now thankyou soo much for taking the time to help me now i can do the rest on my own :)
Glad I could help :b
