4x - 3y = 12
-3y = -4x + 12
y = (4/3)x - 4
^plug this transformed version of the equation into your graphing calculator or do it out by hand.
12
If a graph is a function, it will always have y=... or x=... (or anoher letter equals an equation) for example y= 3x-12 is a function
[ y = 12x ] is an equation, not a 'problem'. The graph of that equation is a straight line with a slope of 12 .
y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)
I guess you mean 4x + 2y = 12 is changed to 4x + 2y = 36. The graph is translated (shifted) up the 7 axis by 24.

4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2
-8x+3y=12 3y = 8x+12 y = (8/3)x + 4 So it will be a line with slope 8/3 and y intercept of 4
Our equation is (2x)(4y)=12 We can divide by 2 to get x(2y)=12 Now just plug in numbers to satisfy the equation. Some examples would be (6,1), (3,2), (2,3)...

-3x + 4x = 12 x = 12 A graph normally shows the relationship between two interconnected quantities, such as 'x' and 'y' . This equation can't be graphed. There's only one quantity ... 'x' . It doesn't depend on any other quantity, and no other quantity depends on 'x'. 'x' is 12, it's always 12, and it doesn't change, and that's the whole story.
