[tex]1.\\ \\ the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\y=2x+1 \\ \\ the \ slope \ (the multiplier \ of \ x \ represented \ by \ m ) \ is \ 2 \\ \\ and \ the \ y-intercept \ (the constantrepresented \ by \ b \ ) \ is \ 1[/tex]

[tex]2.\\ \\ y= \frac{1}{3}x-3 \\ \\ the \ slope \ m = \frac{1}{3} \ \ and \ y = -3[/tex]

[tex]3.\\ \\ y= -2x + 1\\ \\ the \ slope \ m = -2 \ \ and \ y = 1[/tex]
