中考压轴题中经常出现涉及到平移、旋转、剪拼及翻折的题目,解决这类问题需要综合运用几何、代数的知识,请看以下四例.1.平移例1已知,如图1所示,直线l的解析式为y=(3/4)x-3,并且与x轴、y轴分别交于点A、B.(1)求A、B两点的坐标;(2)一个圆心在坐标原点、半径为1的圆,以0.4个单位/秒的速度向x轴正方向运动,问 There are often problems involving translation, rotation, clipping, and folding in the final exam questions. To solve this type of problem, you need to use the knowledge of geometry and algebra comprehensively. Please see the following four examples. 1. Translation example 1 is known, as shown in Figure 1. As shown, the analytical formula of line l is y=(3/4)x-3, and intersects the x-axis and y-axis at points A and B. (1) Finds the coordinates of A and B; (2) A circle with a circle centered at the origin of the coordinate and moving at a speed of 0.4 units/second in the positive direction of the x-axis.
