Question 398262: this is a hard question to put in words, but i have a math equation that looks like this -2y=2-x
i set it up like this y=mx+b
so -2y=2-x and i divide the whole thing by two
i then get y=1 but i dont know how to divide the x
and to graph it after i divide by two i use x as zero and y as what
my assingment calls for two points of each and im not sure if i drop the run over rise and use the next number and just add or subtract what ever the equation asks for. i need to get a slope on the graph please help me
