x-3y=2
-3x+9y=6
He has to plot these. Thank you !!!!
Answer by josgarithmetic(39617)   (Show Source):
You can put this solution on YOUR website! Both equations are in standard form. Find the axis intercepts of both equations.
x-3y=2.
If x=0, then y=-2/3.
If y=0, then x=2.
The points on the axes are (0, -2/3) and (2, 0).
-3x+9y=6.
If x=0, then y=2/3.
If y=0, then x=-2.
The points on the axes are (0, 2/3), and (-2, 0).
Plot the two points for the first equation and draw the line;
plot the two points for the second equation and draw the line;
DONE.
