问题 In the rectangular quadrant system shown above, which quadrant, if any, contains no point (x, y) that satisfies the equation 3x+5y=-2?

选项 A、none
B、Ⅰ
C、Ⅱ
D、Ⅲ
E、Ⅳ

答案 B

解析 The equation describes a line that crosses the x axis at -2/3 and crosses the y axis at -2/5, so it never passes through quadrant Ⅰ. You can plug in points from each axis to verify.
