and then on the same axes sketch the graph of : 4x-2y-8=0
i dont know how to do that..please help
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! sketch the graph of: 6x+9y=36
Solve for y
y = -(2/3)x + 4
It's a straight line, so you need 2 points
Pick values for x and find y.
eg,
x = 0, y = 4 --> (0,4)
x = 3, y = 2 --> (3,2)
Plot the points, draw a line thru them.
====================
and then on the same axes sketch the graph of :
4x-2y-8=0
Do this the same way.
