澳大利亚最主要的石油生产基地是西北部的北卡那封盆地（占全球总产量的73%），其生产的大多数原油出口到新加坡等国。从原油供求情况看，澳大利亚的原油产量仅为其消费量的一半左右，而国内的原油消费少部分来自该国东南原油产区（占全澳总产量17%），大部分来自新西兰、中东等国家和地区。澳大利亚西北部和东南沿海所产原油成分差异大，其炼制工艺和产品品种也有差异。该国炼油厂主要分布在东部沿海。下图示意澳大利亚主要产油区分布。

下表是某工厂6～9月份电量（单位：万度）的一组数据：

月份x	6	7	8	9
用电量y	6	5	3	2

由散点图可知，用电量y与月份x间有较好的线性相关关系，其线性回归直线方程是 $\widehat{y}=-1.4x+a$ ，则a等于（   ）
