Graph y=−5/6x−4 . -5/6 is a fraction btw. i just wasn't able to write 5 over 6

start at the center (0,0)

from there go down 4 on the y axis

now make a dot

from that dot look at slope -5/6

go down 5 (-5)

to right 6 (+6)

mark another dot

draw a line through your both dots

ta da you have graphed you line

if you need , reply with more info. u.
