Question 147321
Slope intercept form is y = mx + b

Given {{{6x-4x+8=0}}}
Assuming this is a not mistyped, 
{{{2x = -8 }}}
{{{x = -4}}}
slope is undefined
there is no y intercept


I figure you had a typo. Let's assume you meant {{{6y-4x+8=0}}}
{{{6y = 4x - 8 }}}
{{{ y = 2x/3 - 4/3 }}}
slope is 2/3
y intercept is -4/3
