You might model each house with a pair of numbers, the 1st indicating square footage and the 2nd indicating price.

你可以用一对数字为每栋房子建模 第一个数字表示面积 第二个数字表示价格。

Notice the order matters here in the lingo, you'd be modeling houses as two dimensional vectors, where in this context, vector is pretty much just a fancy word for list.

注意这里的顺序在行话中很重要 你将房子建模为二维向量 在这里 向量只是列表的一个花哨的词。
