已知一次函数的图象经过点（0，1），且与直线y=－4x平行，则该一次函数的关系式为_____________________。
y=－4x＋1
题目分析：一次函数与直线y=－4x平行，则可设一次函数的关系式为y=-4x+b,∵一次函数的图象经过点（0，1） ∴b=1 所以次函数的关系式为y=－4x＋1
点评：考查求一次函数的关系式，要考生会用待定系数法求一次函数的关系式，待定系数法是一种非常重要的方法

| A teacher started his first job at a primary school and wanted to make a good impression (印象) on the children. When he noticed a boy 1 all by himself, 2 the other children were playing football, he walked up to him and asked, "Are you alright?" The boy told him 3 was fine and the teacher left him.
