题目内容

【题目】第六届北京农业嘉年华在昌平区兴寿镇草莓博览园举办,某校数学兴趣小组的同学根据数学知识将草莓博览园的游览线路进行了精简.如图,分别以正东、正北方向为x轴、y轴建立平面直角坐标系,如果表示国际特色农产品馆的坐标为(-5,0),表示科技生活馆的点的坐标为(6,2),则表示多彩农业馆所在的点的坐标为(

A. (3,5) B. (5,-4)

C. (-2,5) D. (-3,3)

【答案】C

【解析】由已知可得,向右向上为正方向,单位长度是1,用平移法可求得农业馆所在点的坐标.

由已知可得向右向上为正方向,单位长度是1,由点(-5,0)向右平移3个单位长度,再向上平移5个单位长度,可求得农业馆所在点的坐标为(-5+3,0+5),即(-2,5).

故选:C.
