TO GRAPH LINES YOU HAVE TO FIND THE INTERCEPT WITH AXES MAKING CERO THE VARIABLES:

THE FIRST POINT TO GRAPH: 3Y-4X=12 TO FIND X INTERCEP WE MAKE CERO THE VARIABLE Y IN THE

EQUATION SO WE HAVE 3(0)-X=12...............

0-4X=12 4X=12 WE HAVE X=-12/4=3 X=-3

THE FIRS POINT IS (3,0)

TO FIND THE OTHER POINT WE MAKE CERO THE VARIABLE X: 3Y+2(0)=12 3Y+0=12 3Y=12

3Y=12 WE HAVE Y=12/3=4 SO WE HAVE X=4 THE OTHER POINT WILL BE (4.0)

AND WE HAVE THE 2 NECESSARY

POINT TO MAKE THE LINE.............GRAPH (-3,O) AND (0,4) ON AXES "X" AND "Y"
