急急急！！！关于线性代数！！1

Let V={(x1,x2)∣x1,x2∈ℝ} be the set of ordered pairs of real numbers. Suppose in V that vector addition is defined by x+y=(a1x1+b1y1,a2x2+b2y2) for all x=(x1,x2),y=(y1,y2)∈V, and a1,a2,b1,b2 some fixed real numbers; and scalar multiplication by cx=(cx1,cx2) for all x=(x1,x2)∈V and c∈ℝ.
For what values of a1,a2,b1,b2 is V a vector space?

这怎行,课程名都不能,可能学分都有不同.这两门课程也不难. 线性代数只要有初中基础就可学好.概率论与数理统计(经管类)稍有积分知识就可以,这方面分值不高.
