Question 149181
Given {{{3x + 4y = 8}}}  solve for y
{{{4y = -3x + 8}}}
{{{y = -3x/4 + 2}}}

This is in the form y = mx + b, where m is the slope and b is the y intercept

1) So the slope, m, is -3/4


2) Solve for y when x = 8
{{{y = -3x/4 + 2}}}
{{{y = (-3)*8/4 + 2}}}
{{{y = (-3) * 2 + 2}}}
{{{y = -6 + 2}}}
{{{y = -4}}}

Graph is:
{{{graph(600,400,-10,10,-10,10, -3x/4 + 2 )}}}
