+2x%2B3y=9
3y=-2x%2B9
y=-2x%2F3%2B9%2F3
y=-%282%2F3%29x%2B3
now find two points....choose values for x=0 and y=0
if x=0, then y=-%282%2F3%290%2B3.....y=3
first point is (0,3)
if y=0, then y=-%282%2F3%29x%2B3.....-%282%2F3%29x=-3...->..
%282%2F3%29x=3...->..x=3%2F%282%2F3%29...->..x=3%2A3%2F2...->..
x=9%2F2...->..x=4.5
second point is (4.5,0)
now graph it
