the initial expression is:
[tex]3x+4y=8[/tex]So to write it in the form slope intercept we can rest 3x in bout sides of the equation so:
[tex]\begin{gathered} -3x+3x+4y=-3x+8 \\ 4y=-3x+8 \end{gathered}[/tex]now we divide by 4 so:
[tex]\begin{gathered} \frac{4y}{4}=-\frac{3}{4}x+\frac{8}{4} \\ y=-\frac{3}{4}x+2 \end{gathered}[/tex]No M is equal to -3/4 and B is equal to 2e
