1. 2x-4y=4
2. x+3y=9
3. y=9x
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! These are straight lines, so you need 2 points.
2x-4y=4
x - 2y = 2
x = 2y + 2
Pick 2 values for y and find x
y = 0; x = 2 --> (2,0)
y = 4, x = 10 --> (10,4)
Plot the 2 points, draw a line thru them.
-------------
Do the other 2 the same way.
