how do we tell the values of a and b in the following equation: ax + by = 1 they provide a graph with a line angled down and to the right like so \
you might want to put in in y-intercept form
the question is asking which of the following must be true: 1: a>0 and b< 0 2: a >0 and b > 0 3: a<0 and b <0 4: a <0 and b>0 5: a = 0 and b>0
