易和昆826一次函数y=x+1的图像与y= - 2x - 5的图像的交点坐标是什么? -
景柄是15767076047 ______ 因为y=x+1,y=-2x-5 所以 x+1=-2x-5 3x=-6 x=-2 则y=-1 交点坐标(-1,-2)
易和昆826函数y=x的绝对值+1的图像y=x+1的绝对值的图像与y=x+1的图像的关系 -
景柄是15767076047 ______ y=x+1的图像先向下平移1个单位得y=x,将x<0的部分关于x轴对称得y=|x|,再将图像向上平移1个单位得y=|x|+1 y=x+1的图像将x<-1的部分关于x轴对称即得y=|x+1|
易和昆826函数y=x+1的图像是不是函数y=x向左移一个单位? -
景柄是15767076047 ______ 向左移了一个单位,原来经过0,0;后来经过-1,0
易和昆826x - y+1=0的图像是什么?怎么画出来的? -
景柄是15767076047 ______ x-y+1=0 y=*+1 由y=*的图像,沿y轴向上平移1个单位,可得到y=*+1的图像.
易和昆826如图一个正比例函数图像与一次函数y= - x+1的图像相交于点p则这个正比例函数的表达式是—— -
景柄是15767076047 ______ y=-2x解:∵正比例函数图象与一次函数y=-x+1的图象相交于点P,P点的纵坐标为2,∴2=-x+1 解得:x=-1 ∴点P的坐标为(-1,2),∴设正比例函数的解析式为y=kx,∴2=-k 解得:k=-2 ∴正比例函数的解析式为:y=-2x,故答案为:y=-2x
