Thank you very much for your help. One more question... if the problem had been a minus ((8x-4y=12)) would it still be an addition on the right of the equal sign... or would the sign have changed?
if you change all the signs by a negative sign you get the same equation.
-(8x+4y=12) or -8x-4y=-12 or -4y=8x-12 or y=8x-4-12/-4 or y=-2x+3
---------------------------------------------------------------------
IF THIS IS A LINE EQUATION THEN:
8X+4Y=12
4Y=-8X+12
Y=-8X/4+12/4
Y=-2X+3 THIS LINE HAS A SLOPE=-2 & A Y INTERCEPT=3 (0,3).
GRAPH FOLLOWS.
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = -2x +3).
