[tex]the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\ 2x+8y=12 \ \ |-2x \\ \\8y=-2x+12\ \ /:8\\ \\y=-\frac{2}{8}x+\frac{12}{8}[/tex]

[tex]y=-\frac{1}{4}x+\frac{3}{4}\\ \\ m=-\frac{1}{4}[/tex]



[tex]x-2y=0 \ \ | -x \\ \\-2y=-x \ \ /:(-2)\\ \\y=\frac{1}{2}x \\ \\ m= \frac{1}{2}[/tex]

2x+8y=12
-2x        -2x
8y/8=(-2x+12)/8
y=-0.25+1.5

x-2y=0
-x       -x
-2y/-2=-x/-2
y=0.5x
